ok so i have a 91 ef hatch that has been converted to obd1, it has a d16y8 motor in it. The car ran for about 3 days but it sputtered up until about 2000rpms, because the timing is off. But a few days ago i went to start my car and it cranked over and ran for about a sec and died immediately. i was told it could be multiple things. i replaced the alternator cuz it was bad, and still same thing, replaced the dizzy cuz the module was bad and the magnetic things inside were cracked i cant think of wut there called, also put new spark plugs in, new fuel filter and new intake manifold gasket, and yet the problem still persists, i have no clue as to what it could be now, im thinking maybe clogged injectors but im not sure, if you know anything or have had the same problem please tell me thanks, Kyle

 

In all of that, I don't see u saying anything about correcting the timing issue...

Did you?? Beause if you didn't that could definitely be....IT.

 

well no, but why would it just stop all of a sudden and not want to run??

 

Can you hear the fuel pump when you turn the key?

 

yes the fuel pump works cuz i checked the fuel line to make sure it was getting fuel, and i can hear it

 

Check your timing. And fix it if its off enough it won't start. Or you could of bent valves do you hear a ticking. At all???

 

x2 on the timing issue, or bent valves.

 

umm im not sure it wont run long enough for me to hear anything but i dont remember any ticking, but ima check the timing for sure tomorrow

 

timing and if not that could be ignition switch. right after if fires up try not to let up all the way on the key and kinda keep it in between start and the run. ive seen that happen before

 

NO?....

Uh yea, bet you a nickel it's because your timing is off like I said initially..

 

well im going to check it tomorrow, and ill update you guys if it starts up and keeps running

 

well i was a little too busy today with college paperwork to actually change the timing but i did have time to check it by rotating the number one cylinder to top dead center and the timing is off by 180 degrees holy sheeeeet!! thats def. what the problem is lmfao

 

Ya that deff is your problem lol

 

ok well i did the timing and still nothing, im guessing i should get the injectors checked to see if there good or not.

also found out that my ecu makes my buddys coupe idle at 2k rpms, makes his check engine light come on and makes a ticking noise in his engine, but ususlly his idles at 1k rpms no CEL and no noise

 

why would your buddy's car idle at 1000 when stock is 700? Also you should check your grounds as they're probably bad.

 

well my buddys car doesnt matter plus its 750 not 700, i was just stating what my ECU did when plugged into his car.
I will check the grounds today and post on here if anything happened thanks

 

spark, fuel, timing. 3 things needed for a motor to run. stop randomly replacing things and get out your voltmeter.

 

lmfao im not randomly replacing things im going my the book, the stuff i replaced was bad, if your alternator or dizzy is bad your car wont run obviously, mine were bad, i timed it, its getting spark clearly if it cranks over and its getting fuel up to the fuel filter, thats why i need to see if the injectors are good or bad....

 

main relay? did you put a new dizzy on it or a used one?

 

well ppl said you should here a click after the fuel pump primes and i heard a click so im guessing its good

i bought a brand new one for the y8

 

CKF, or TDC, CKP, CYP (in dizzy) or some other sensor, most of which are all contained in the distributor.. If you have the helms, check out the little sensors.. Those would be enough to cause the car to start but not run. If the sensors aren't bad, the wires to there are.
