KA24E won't start. Typical culprits tested

[justy90240sx]

ok so the car is a 90 240sx ka24e. i have a second car i have been switching parts with to try and find my problem. the car has new cam chain, tensioner, guides,injectors, distributer cap and bug. the symtoms of the car are, is cranks freely, has spark, plugs are wet, injestors work with a noid light, fuel pressure was good and its in time with a timing light compression checked at about 130 give or take, and leakdown was good. switched out the distibuter, ecm, maf, ignition coil, and all parts are good, because they came from a running car. the only other things i can think to try are the o2 sensor, and the powertransistor thats mounted on the ignition coil braket. if anyone has any information that could help me it would be appreciated greatly

[srpowered240sx]

you have fuel, spark, and compression......you should have fire. when did it run last?

[justy90240sx]

heres the story i bought the car needing a cam chain and and tensioners. i installed them the car ran great for 36 mi exactly before it died while i was driving and hasnt hit a lick since. like i said it has spark, comprssion, and fuel. but i dont know if its getting spark or fuel at the correct time. if you have any suggestions i would appriciate your info thanxs.

[srpowered240sx]

take the v/c off and look at the timing chain. maybe something bad happened up front.

[justy90240sx]

i did take the valve cover off and everything looked to be in good order. im stumped here really need some help

Could be something wrong with your ecu? Have you checked your fuses? Try the fuse box in the engine bay, check them all. I had the same problem once and it was a fuse.

Car runs without a 02 sensor plugged in, so its not that.

I had a similar problem. Def. Check your fuses, especially your fuel pump fuse. I didn't understand why my plugs were wet when I found out my fuel pump wasn't kicking on. I soon learned later that when you crank over the motor, it creates a small suction, just enough to get the plugs wet when ever there is fuel in the line, sometimes. (such as in my case) When you turn your ign. on, unscrew your fuel cap to see if you have pressure. If you don't, try this.

After you check your fuses and pressure in the tank, open up your gas cap and release the pressure. (if you haven't already) Next, go to your hatch/trunk and pull up the carpet on the right side. Use a (If I can remember correctly) a 10mm socket and take off the cover (maybe a 12mm, not for sure) Next, use a philips head screw driver to take out the six screws holding down your fuel pump rack. Pull up the rack and check your wires. Make sure everything is connected (my ground or negative[black wire] was broke)Have a friend turn on the ignition and check and see if the pump is kicking on or not. May or may not be your problem.

If this isn't the problem, then I am very sorry to of wasted your time.

[justy90240sx]

ill check the fuel pump like you suggested as well as check all the fuzes again i hope i can find the problem of the car is goin to the shop and i hate other people working on my car

GL man.

theres one other thing when i used the self diagnois on the ecm. in blinks likes this Green, red sametime.then green, red 2 times sametimethen green, red 3 times sametime

[skatermatt180]

If there was a problem with the ECU, that only mainly looks at emissions, but your car will run even without emissions. It might give you a code for the MAF or something, but you said you replaced those things. Unless there is a short in your wiring or a cut wire, that shouldn't be an issue.

Let us know what you find with your fuses, usually its such a simple thing that could lead to an engine not running. And checking your fuel pump is a great idea as well.

GL man, let us know!

[skatermatt180]

and ajones1229 I don't think you are wasting his time...seems like he is up to try anything. haha, been there done that.

Ditto.

I don't really know anything about the ecm deal, mainly because I've never had to mess with it before. So I can't really help you with your light situation. Hmm... I'm telling you, It won't take more than 30-45 mins for your first time taking out your fuel pump, so do so if you haven't. I've had to take mine out so many times that I can take it out and put it back in, in under 5 mins. No Joke.

You also said that you put a new timing chain on it? Check and make sure your timing is set correctly. Hmm... What else..

Idk...

I'll comment back when I think of what ever else it could be, if you haven't figured out the problem by then.

[justy90240sx]

i checked the fuel pump, and fuzes. like you suggested and all fuzes where good. the only thing that seemed fishy was the fuel pump should prime whith the ignition switch in the run posistion right. well sometimes it does sometimes it doesnt. but always pumps while cranking. the ignition switch is acting weird when i turn it back to the off posision sometimes the brake light oil light and seat belt light on the dash dont turn off with key off and out. acts like the switch is still in the on posision. think it could be my problem. i think im pretty good when it comes to trouble shooting and im stooped boys appriciate the help. the car goes to the shop on thursday if i cant find the problem tonight so if u all have any ideas they are appriciated. one more question the control module (mounted on the coil bracket) can it fail and the plugs still spark?

No clue. If it's not that, it may be something in your wiring... maybe.. idk. I tryed. GL with every thing. Tell us what it was when it comes out of the shop.

[trahc]

can you check the fuel pressure ? will the car even attempt to crank?

[justy90240sx]

its in the shop now i droped it off yesterday
