Help new build won't start.

[boosted KA24DE]

Finally got kat finished but it wont turn over.
got my e-mance ecu in.
Got spark and fuel but does not seem to be popping.
timing is good as well as dizzy could this be the coil?
spark seems very weak.

[boosted KA24DE]

Wow what pals I have.:down: No one to interject with any comments.
Will wire up new n62maf today, check dizzy again and blaster coil.
Lets see where this goes.:tweak:

[orion::S14]

Is the battery fully charged???...+12.5volts (weak spark will come from a low battery, when the starter is sucking up all the current to turn the motor over).

How did you determine the timing was good, if it hasn't started? That's probably the #1 messed up thing on KA builds/rebuilds. If you just lined up the dots and popped it in there, then that's MOST LIKELY your issue. I've done it countless times, and still get it wrong sometimes.

what i have to say will most likely have nothing to do with the starting but your mistake is the E-Mance ECU. my ka-t blew and do you have a built ka? if you do then good luck on building another motor.

as for the start up, double check your wires and make sure you installed them correctly. do yo have the msd blaster coil ss?

[boosted KA24DE]

oem blaster.
Timing was done by have set timing chain to TDC along with cam lobes
being properly positioned along with motor being in correct stroke.

I'm having trouble finding good right up on timing. had alink but lost it.
FSM beats around the bush and is fair at best.

Yes fully built motor and yes e-mance. Anyone can blow a motor for any odd number of reasons. I don't play the blame game, just play the game.

[boosted KA24DE]

Yes i understand i cant check timing and dial it in till its running but as far as having timing on cams and pullies thats what i meant. this is very frustrating.

if i were you i would get a msd blaster ss coil. my stock one went out couple of miles after i got my ka built. it wouldnt let me start up when hott (which has nothing to do with your problem)

anyways, as for the ecu, who spends all that money building a motor and then buys a cheap ass tune :faint:? good luck with the tune.

lmk how your car turns out after you double check everything

[boosted KA24DE]

Hey man money is tight got three kids and not wanting to give up on this.
Keep hope alive is what i say. I got it to start for 5 seconds but i stopped holding the gas open and it died.

[fcdrifter20]

timing timing timing timing. have seen this problem many times. 9 times outa 10 when i go check it out timing is off. u gota make sure that rotor is before #1 not on it.so if u have to pull cap off, install dizzy and see wher the rotor ends up then adjust as needed. this is most likely ur issue.

i understand that, its the same with me because i got school bills. i wasnt trying to bash on you just trying to help you save some money by not blowing up your freshly build motor.

my built ka never started too but then i remember it was the builders fault by installing the cams wrong, intake on exhaust and exhaust on intake but then he got the car started without switching them around so i still think it was timing.

same base map you were running, i have running on my best friends ka for over 2 years.. never a hickup/never a glitch just 12 psi daily.. i think there was something wrong with your setup somewhere else and that is why your motor blew up.

i guess its easy to blame a tune and not shitty used injectors or maybe a dying fuel pump, incorrect base timing or 10 year old waste gate that could be going out... the list goes on

a tune is only as good as the build it is supporting.. i guess i need to put a disclaimer about using used parts and my tunes.

i have sold hundreds and hundreds of tunes and have only a few complaints, you're one of the biggest complaints i have had. cant please everyone and i know this but i do stand 100% behind my tunes and wouldnt sell anything that i didnt feel was safe. hell how do i have a 720whp ka-t? it should of blown up years don't you think?

anyhow back to subject at hand, OP: check your cam timing it sounds like your timing is off

Hey I been the one emailing you back and forth. I'm gonna get my downpipe made first with the o2 in proper place with wideband no reason to keep trying to speed things up. i have another car so i'm gonna slow down and take it a step at a time. Its been five months on this build so whats a couple more, not gonna hurt. I'm gonna check the cam timing again just in case. And by the way J do you have the cable for the diagnostic port so i can view the codes and live data like on your site. I read the codes off the ecu lite and it goes 2 really slow then 3 slow again then 4 really fast so i dont know what to make of it. You asked for me to read the codes and i did.

HA! first off i had brand new wal-bro fuel pump and injectors from d-werks.

when i got your tune it wouldnt start up in the morning (cold start) til couple of tries. when it started my car would idle alot better but then would run like crap. it was jerking on the begining or 1st, 2nd, and a little on 3rd gear til a certain RPM then it would stop. i remember you said that you tuned my 450CC injectors at 460cc on the tune because it was flowing at that rate. and then about 1 week later when i was boosting BOOOOOOOOM! motors gone. so my question here is was it my brand new parts that caused my motor to blow? or was it the tune being tuned for 460CC instead of 450CC like the chart says when i purchased the injectors from d-werks? i dont know but this is a easy answer.

remember all the parts i had were BRAND NEW except the turbo (turbo wasnt messed up).

all im doing here is trying to save people from going through what i had been through.

now i have a built KADE with a Enthalpy ECU and i love it! been running for almost a year now with no problems since the day i installed it. :hsdance:

goodluck in your business jason

since when are deatschwerks brand new injectors? they are used drilled/reflowed injectors which flow funny and different than other injectors on the market, ask any tuner about reflowed injectors vs real 450cc

you are running same injectors on your setup right now? im impressed if you are.

how was your cam timing then? was it checked and double checked? what blew on your motor? ring lands? if so its from too much timing, boost spike or both (granted your injectors were flowing what they claimed and fuel pump/fpr were doing their job) like i said that tune has been going strong on my best friends car for over 2 years no hiccups so something is wrong here. im reviewing your tune right now you have 14 degrees total timing up top under boost so i highly doubt my tune blew your motor unless your compression is somehow above 10.5:1 from carbon buildup or something else.

Also, importdude was running my 450cc tune on his ka-t for a while and his motor never blew up until he upgraded to 850cc, turned the boost up and get a retune from me and he's been rocking that ever since may... wonder why his motor didnt blow?

first off you tune the ecu at 460cc instead of 450cc and you told me that on the phone and even said that you did it because it was flowing at that rate on the paper and it would be fine.

btw, before i bought your tune my car wasnt giving any hiccup or problems. it was tuned by my afc neo, and the only reason why i decided to go with a ECU tuned was to make my car run at 100% power. remember this, when my car was still tuned by the NEO, it ran for over 2 months if i can remember with absolutly no problems and it was with the 450cc from d-werks.

as for my timing it was done by me and my mechanic and not just that, when i took my car to get tuned before i purchase your ecu tune, the person who dyno tuned my car checked my spark plug gaps and recheck my timing. i know FORSURE it wasnt wrong. my rings blews in the same week of the tuned installed.

one more thing is my motor was completly stock and perfectly running good before i turbocharged it.

how much boost were you running? any spikes? how big was your intercooler? what injectors are you running with your enthalpy tune? there are tons of variables of what could of happened but i still stand by my tune i might have a few unhappy customers but i have hundreds who are happy and its just not right how happy people dont go on fourms like yourself to complain.

glad your car is running good and you're happy.

if you have anything else to say please take it to PM so we don't threadjack this guys thread

OP call me 619-467-5446 if you need any help.

it was a stock wastgate and it wouldnt let me go any higher than 8 PSI, no spikes at all, and i had a GREDDY TYPE M FMIC again it was BRAND NEW!
as of rite now i have tomei/nismo 740cc on built KADE

i would of never complain on forums but then just had too because it really sucks when you spend up to $2,000 on parts and then one thing caused everything to go down the drain. just when i thought eveything went well it completly turned around. im not trying to put you out of business, just letting everyone how my experiance was.

btw im not even sure if i still have your tune.

again goodluck in your business (E-Mance)

I re did the timing. Seems like the dizzy was moving as i was putting it in.
adjusted the rotor and lined up perfect. Them I cranked but no spark this time. tried another coil and it started right up.:goyou: now the bad part, tried starting again and now no spark again. I might be burning coils is this possible. Easy fix or not oem coil current but upgrading to msd. still need help.

[Ceepo]

are your fuel lines backwards.... i know you said you got fuel, when i tried to start my sr it wouldnt fire, i had spark, fuel, compression, and timing, my problem was i had fuel, but no fuel pressure, it wasnt misting out the injectors, i swapped the fuel likes around and it fired up the first time...

No.....:confused:not fuel just no spark.blew 2 coils just ordered bkr7e and msd blaster coil. Lets see what happens when i install these. only code i get now is 34 (detination)knock sensor bad? Still no clue why i blew 2 coils. Harness is untampered with.:wtf:

[Ceepo]

bad grounds?

[nosajton]

either bad ground, bad ignitor or bad ballast resistor

[hotlavaflow]

Everyone said timing so I'll leave that alone. I have an MSD coil got rid of the stock one during KA-T build.

Did you use a spark tester to actually make sure your not getting spark? Do you hear the fuel pump prime before attempting to start? If it keeps turning over strong but not starting it wouldn't be a ground issue.

BTW
Running an Emance tune for quite a while with no problems at all.

[boosted KA24DE]

I checked all the grounds. Will look at the igniter, resister, and hook up new coil. Coil came in yesterday just waiting on new bkr7e plugs coming in today.
So will :jerkit: this weekend and see whats up when i try to start it. :wan:

[boosted KA24DE]

Here we go again...
Installed msd coil...great
Installed new plugs BKR7E...great
and now lets crank it over.....result
It had a rough start,idles like shit,I cleared the ecu for codes and intalled a new knock sensor cuz i was getting code 34 and it still will not idle on its own.
It's running pig rich on 850cc denso injectors.help.. not happy with this mess at all. the timing is spot on. i'm fouling plugs at start up. way too rich.

[boosted KA24DE]

Found some info on a site and this is what my 850cc denso will run at....
Flow rates:
3 BAR - 850cc/min
3.5 BAR - 905cc/min
4 BAR - 980cc/min
now if my bin file on the ecu is set for 4 bar...well then i will run crazy rich..right
There are different denso 850cc sidefeed injectors so let say my that the right ohms setting in the bin file is not right then the whole setup would be wrong right. any thoughts?

[boosted KA24DE]

yea, keep me updated. give me a call tomororw if need be as i'll be at SEMA tue-fri
I'm still at it trial and error. could it be that i need to be at 3 bar on the ecu for me not to be dumping so much fuel. it runs sometimes but rough as hell and way too rich.

[importdude]

do u have a wideband?
alot of things can be messing up
little vac leak ect ect

when u get it right it will be awesome

im running the 850cc+emance E85 tune

made 380whp 366wtq

my car starts everysingle time no problems nothing

I'm happy your is running but mine ain't I have checked everything. either the tune is too rich or its something so stupid that i would burn the car for it driving me insane.
no wideband yet.
Are you running at 4 bar?

Again, how do you know the timing is "spot on"...????

If you haven't checked it with a timing light, it's probably way too retarded...and you're not getting complete combustion, so it seems as if it's running too rich (spark timing too late for the fuel in the cylinder to all burn).

Still sounds to me like a timing problem.

My base timing is spot on. If you have a better write up other than what I have found then be my guest and show me. Base timing at tdc is spot on is what I mean, I went over this on page one of this thread.

[nosajton]

Also are you sure your fuel rail isnt leaking past the orings? you need to remove the fuel rail bolts and have someone turn ignition on and off a few times to pressurize the rail and see if any fuel comes past orings


is the ecu still throwing any codes?

I mean check it with a timing light. The initial timing may be OK, since the car will start.

If it will run, have someone else start it...and hit it with the light.

Chances are, it'll be at ~5 BTDC or something...and that can cause most your issues (unburnt fuel, poor ability to rev, fouling plugs, etc...)

[boosted KA24DE]

Hey Guys here is the news. I now have done everything in my power to get this car running right. I put my old injectors back in and stock ecu and maf. the car starts and runs on its own......meaning, there is some thing wrong with the tune or the ecu that was sent out. Hate to break it to you J but Ima have to return this to you. If you want another go at it I will send you out my ecu to get chiped and then we will see if it was a bad ecu I was sent. There is no other explanation. Everything is hooked up, grounds,plugs,wiring,piping.o2 is in place just finished downpipe.
I even had a friend who is a mechanic lui come over and conclude that it is the chipped ecu. he confirmed the base timing and said it was right. then we timed it with his gun and it ran,idled perfect at about18-19degress on the crank pulley notches. by the way my 850cc injectors are not leaking past the o-rings. I now have all the new stuff back in and again it wont start... its the tuned ecu. not happy but lets make this work. willing to work this out. I believe.

[nosajton]

call me tomorrow we'll talk about this

[boosted KA24DE]

Ok got new Dizzy got new chips for ecu and boom the car starts right up.
It will not idle by itself yet but is a hell of alot better than it was before. its not surging so bad and I only have to open trottle up a little. I am checking for any vacuum leaks and going over everything. checking to see if idle control valve is not stuck or something. It will foul plugs still if I try to start it again. a little rich but not as much as before and now i get 55 code for ecu being OK:bigok:. Good signs so far lets see if I can get it running on its own now getting apexi air filter for z32 maf now should be here soon. And yes I checked the maf. got it from abuddy with a sr20det sentra and we just swapped his with mine and his car runs fine so its good. If any one has any ideas for helping me out, much thanks.
