KA won't start (I searched and found nothing)

[ShiftLock]

I did a search on this and the only thing that came up was the spark plugs could be bad, anyways.....

I started my car today and it idled at 500rpms for about 2 seconds, then it stalled. I tried to start it again and I can hear it crank, but nothing! I bought a battery last month and my radio still works, so its nothing electrical. It was running like a champ last night, I dunno what can be the problem besides spark plugs or would that be a good place to start? To me it seems like its not getting gas cuz i couldn't even smell any when i kept trying to start it. BTW, I just got it back from the shop yesterday cuz they replaced my valve cover gasket, maybe they screwed something up?

check to make sure you haven't blown the fuel pump fuse and that the fuel pump is turning on.

ya know what, i'm having the SAME problem with my car. i just finished my turbo install the other day and got my downpipe elbow fabricated today. it drove home just fine and was driving fine without the elbow for 1 day. well tonight when i went out to my car to go for a ride, i cranked it up and it ran for about a minute then it died out of nowhere and wouldnt start back again. i thought maybe it was my new battery (410 cca) but then i hooked up my old battery and it wouldnt do it with that one either. yes, my fuel pump comes on because i can hear it hum when i turn over the ignition and No the fuel pump fuse isnt blown, i checked. this is awfully strange and is bugging the crap out of me.

no, there are no undone pipes in my turbo setup, everything is good

Shiftlock- check your fuel pump fuse and your fuel pump. Theres a writeup on changine your fuel filter here (http://www.240sx.org/faq/articles/fuel_filter_replacement.htm) . It will tell you how to test for fuel pressure in the line.

Superhoss37- check that your plugs arent fouled. What fuel setup are you using??? Did you replace your fuel filter when you turboed it??...if not the Z32 Turbo fuel filter is an upgrade I believe. Is your FPR under vacuum?

Mine wont start either! =( Well, it kinda does but dies right away. starter kicks in but after it turns over, it sounds like crap. spark plugs, injectors, or cylinder problem? im a noob so if someone could help me out that would be great. I smell fuel afterwards if that helps any... thanks

[misnomer]

ShiftLock: I personally don't know how changing a valve cover gasket could cause the car to not start. . . Check for fuel flow.

Matt: sounds like it may be flooded (too much fuel, not enough air to ignite it). Let it sit overnight before restarting. Definitely check your spark plugs, let us know what, if any, residue is on them.

[superhoss37]

well, tried again tonight and no luck whatsoever. i filled the tank half full with gas and that wasn't the problem. the fuel pump comes on like it should because i hear it hum for a minute then go silent again. im getting fire because i tried the old screwdriver spark trick. what else...oh yea,i tried rolling my car down the hill in 1st gear then dropping the clutch to try and roll-start it. NO LUCK. it just tried to roll over and wouldn't. i can't think of anything else. this car was working FINE until last night. the turbo is on and working properly and i have no clue what the deal is because last night it turned on and ran for 3 minutes then stalled out and died and havent started it since. PLEASE HELP

Fuel Filter? or maybe the fuel injection circuit/fuse or relay whatever. i think it's a fuel problem...

[Matt_240]

misnomer - thanks for the help man. it started up after a 2 hr wait. i guess it was just flooded. im going to check my spark plugs to see if that was part of the problem. thanks again

i installed the walbro 255 lph fuel pump about a month ago and have had no problems with it whatsoever. it works like a charm.

my fuel setup is...

same stock fuel filter(unchanged)
walbro 255 fuel pump
s-afc 2
370cc injectors


havent checked the spark plugs yet but is it possible for ALL spark plugs to be bad all at once like that? i just dont understand the car dieing like that unless it's the distributor like you said. do those distributors just go bad like that?? and would it be possible for the fuel filter to be so clogged up like that??

ive got to keep my dad interested in fixing this problem otherwise he's going to take it to nissan

Did you check your compression? can you keep the engine running if you give it gas after starting? Did you check your timing (important!)

thanks for the info guys, turns out that my fuel pump was shorted out. So I guess I'll replace that asap.

[superhoss37]

well.... after letting nissan check out my car, they tell me that my cylinders are flooded with gasoline. i believe that this is true but they also tell me that they need all my stock parts before i installed the turbo because there are hidden sensors in the parts that i dont know about. now, arent all the sensors just like the iacv, egr, and both o2 sensors???

just wondering if this is what flooded the engine....

the day i took my car to the muffler shop is the day my car stopped running and that is ALSO the day that i found that the bolt on the back of my hks ssqv blow off valve was missing completely. does that bolt that loosens and tightens the valve turning up missing have anything to do with my engine becoming flooded??? that is the only thing i can think of because that is the only thing that changed in my setup.


i dont want to pay an arm and a leg for them to fix my car for me so what would i need to do to fix it? could i just siphon the gas out of the engine and replace the bolt on the blow off valve or is there probably more involved??

[the head]

sounds like you cranked it too long without the thing fireing ask them what sensors they are looking for get names of them replace the spark plugs and see if you have a spark

[superhoss37]

im getting a spark off my wires but could the gas in the cylinders have caused the spark plugs to possibly go bad??

could i possibly fix my car myself by just siphoning the gas out of the cylinders and replacing the spark plugs???

[Var]

I suppose you could take your spark plugs out to dry. Leave the holes for the spark plugs open cause gas evaporates quickly. Give it an hour but dont let any dirt get in there. Then put your plugs back and try to fire her up. Maybe you were running so filthy rich that when you take your plugs out they will be fouled. Or maybe you just blew a head gasket...naaww. couldnt be. or could it? muhuhahahahahahaha

EDIT: I just thought of something else. If you took your airbox off which has the IAT sensor(intake air temperature) on it maybe it's reading at it's lowest possible reading which is -40 degrees so it's compensating by adding hella fuel cause it takes a lot more fuel to start a car in cold ass weather.? just a thought. good luck

[superhoss37]

that makes sense about the intake air temperature sensor but dont most people just leave that unhooked? i dont think ive seen any turbo ka's with that hooked up...or have i?

[lhracer05]

Just a thought but maybe if you were running the BOV to atmosphere, there's a chance that that bolt u found missing could have made it run even richer and caused it to mess up the air-fuel mixture...Anywho, good luck and hope you get it running.

[superhoss37]

now what im thinking is that my dad kinda screwed it up in a way. my dad drove my car back home from the muffler shop and on the way home one of the pipes blew off but only half way where it would run but just barely run. he said it was jerking really bad. maybe that was it. it was getting the right amount of fuel but very little air.
