So just got done installing my sr finally into my 13 and checked the harness, everything is connected how it should be according to frsports diagram, from the ecu to the harness for the car. except the speedo cause there is no right up for that and i cant figure that out, or havent really tried, so i went to start up the car and it kind of cranks not really and it makes a thud and stops trying to even turn apparently. thinking maybe the battery is dead or going to die, i tried with it when someone is jumping it, i still got nothing just a thud as it kind of as if it were to lock up... im curious in your opinions what should i look for or where should i go to next. I am also going to check tomorrow if i can manually turn the motor

So you installed your SR, followed the diagram, and when you try and start it turns over but falls on its face ? Just trying to understand correctly.

Did you gap the plugs correctly ? Stock gap is .036
Maybe try re stabbing the CAS, follow the diagram on FRsport.
Set the car to TDC where the crank is on tooth number 2, and push the CAS in. set it to the middle. and try again.

Are you using a stock MAF ? or Z32, or what. Are you completely just a stock SR ? Maybe your MAF is bad ?

Again those are just simple checks, do you have fuel ? spark? ext. Start off there and just go from there. Little more details in what your asking.

its a stock sr with a front mount, I have stock maf, and tomorrow ill check the plugs and yes simply to put it, it falls straight on its face lol which sucks, and im going to even double check the cas and timing marks tomorrow, im just pretty much asking what could cause the motor to fall on its face, no crank really. I checked and i do have fuel as well, it primes fine

If u don't have spark check ur ignitor, maybe bad coil packs or harness, or bad CAS, could be ALOT of things man.

ok so went to check the cas and removed the spark plugs to find out the motor is flooded with fuel... im going to have to research what can cause this but that looks like that is probably the main suspect now

Make sure you get that fuel out asap before it gets into ze oil... Check fuel injector o-rings.

make sure you connected the fuel lines to the correct places, iv scene this happen be4 ppl mix the fuel lines up

Double check timing. Most of the time when people complain of the car falling on its face on here its usually a timing issue. And if its flooded with fuel sounds like you may not be getting any spark.

i bought new spark plugs and want to buy o rings all round but dont know if the ka24de is interchange able if so ill go to nissan tomorrow to pick them, if not where would be my best source to get to them. I also did soak out alot of the fuel and left it uncovered so it will evaporate out

fuel lines are correct btw. fpr to return and the one from the filter to the one in between the manifold, I was also told the fpr could be a cause for this any confirmation on this?

ok so replaced the o rings and the fpr yesterday as the parts came in, time to turn the key faith up but reality not so good, motor flooded with fuel.
Things i did this time, reset the cas, new o rings, new fpr, and new spark plugs. im no thinking it might be leaky injectors, also what are the possibilities that my coil packs are bad? would they cause no spark and have the motor fill up with fuel as well? any and all help is appreciated, but for the time being ill keep everyone posted on what i do, next is injectors and o rings again

make sure the ground for the coilpacks is hooked up to the head. I wasn't getting spark on my SR swap and that was the problem for me.

stuck injector?
I had this problem on my sr once.

This is what i did.
I pulled the fuel rail off and pulled it so i could see them quirt.
Then i had a friend crank the engine as if i was starting it.
The bad injector would squirt a large amount of fuel, while the rest would mist fuel.

No coil pack would not be the problem. Even if one did not fire it would not cause flooding.

have you checked the Ignitor?

BestOneLeft
05-21-2011, 02:52 PM
car starts so its not the ignitor.
If ignitor was out the car wouldn't spark and wouldn't start up at all. he has spark.
He has a fuel problem, flooding the engine.

ok so i just got a few injectors thanks to a member on here, my question is if its a stuck injector would i have to crank the motor and watch it squirt or will i be turning the key all the way on without cranking it? cause i turned it all the way on without making the motor crank and it doesnt squirt anything (im sure that shows my o rings are good?) also is it fine i crank the motor without the plugs and coils in to test the fuel injectors if i was to check to see which injectors are bad

Sounds like a stuck injector something similar happened to my ka and I did something similar to what the member above said and pulled my fuel rail and had someone crank the engine and found that 2 of my injectors had fuel drip out while the other 2 had a very fine mist. You have a fueling issue not a spark issue.

ok this is starting to really suck i switched out the injectors and yea still flooding, tomorrow morning im going over the interior wiring one more time and i pray i get this this time......... im also going to double check the harness is connected to the right ones, even though im sure im right i just feel like giving up trashing sr's and saying fuck yea back to kat's
hahha i dont know

Sounds like a timing issue to me. Too much fuel- too advanced timing?

na12uto
05-30-2011, 12:28 AM
it wont even start if locks up right away so there isnt a way for me to check timing besides the idea i did reset the cam angel sensor to wear it should be from frsports specs

Have you done the check on the fuel rail?

Remove the 12 mm bolts holding down the fuel rail
Pull the fuel rail away from the intake manifold and up so you can see the bottom end.
Turn the key on and crank the starter (The injectors will not fire is the CAS does not spin so you must crank the motor over)
You will be able to see them mist the fuel.
If you have a bad single injector it will be just 1 dropping fuel.
If all four are flooding then its not the injectors. This would be the signal is staying on.
So it would be ECU or wiring related, Possible ground ect.

Its obvious that the problem is open injectors, or Bad O Rings.

I wrote this down before I saw you changed the injectors out. (ill leave it as a reference)

I would try the ECU Next. Or at least unplug the ecu and plug it back in. Make sure

How quickly does it take for the engine to get flooded? If it takes awhile, try to unplug the injectors to get it started, then once it starts plug them back in.

And how are you getting the fuel out once it locks up? If you let it just sit in there/work it's way into the oil, bye bye compression. (Ask me how I know). I had same problem where too much fuel was getting dumped in, so I took out spark plugs and cranked it to get all the fuel out (cover up any spark sources).

That is the best way to get the fuel out. You should be doing this often.

are you saying with what you did was wrong or thats the way you took the gas out?

ok so i see how it should be done and i actually got the car to start today and after about 10 seconds it died and i cant crank it by hand...... I can crank it backwards a little bit then it doesnt turn and same thing back foward til i get it to a certain spot.

I also had the ground to the coilpack correctly set as well.... So what does it mean now that i cant turn it by hand....

ur still flooding
u need to find out which injector is flooding engine
by pulling rail and checking by turning over like the others told u
but remove the fuel first
like others said
bad injector o-ring
stuck injector
or bad ecu signal to injector

Best way = Take out spark plugs, cover up spark sources, crank engine to shoot out fuel.

Worst way = Let it sit in there...

It's flooded/hydrolocked... I suggest not trying to manually crank it, and to not try to start it anymore until you get the fuel figured out. Also, change the oil, just to make sure no fuel got into it, etc.

is your MAF good? i know you said it was stock but have you checked it with a Dmm? (Digital Multi Meter) i think this is your answer...lol hopefully

maf wouldnt really matter to get the car to start, it can start with out the maf, but anyways do the spark plug test, take one of the spark plugs out and connect it to the coil pack externally, then stick it close to a ground and see if you get a spark..be carful with the gas situation too, drain it out before you do the test just to be safe, if you dont get a spark then i highly suggest that you unloom the coil pack subharness and check all of the wires, keep in mind that all of the four coil packs ground to that tiny wire that grounds to your block... hope this helps

I am having the exact same problem.. any luck?
BUMP!!!

ok so I took apart the block and found nothing that should be causing it to lock up. I am going to take apart the head next..... so im going to buy a gasket set... the only thing preventing me from rushing this is the idea i have to pay for my wisdom teeth to be pulled next week or two so thats what im saving for

ok so i decided to not create a new thread as this will be a follow up on whats going on and as well for any help related things i could turn too...
head off still locked up
nothing seems out of place just looking at a few things that could seem potentionally bad

i dont know i was going to go through the fsm today, this is the first motor i ever tore down so for me to not touch something and it fall off i was thrown off.. Im just learning everything as i go through it
