KA starts up fine then dies.

[maker_moan]

To start it off, I have a 92 nissan 240sx coupe with the ka24de. My car starts and run totally fine until that moment it just straight dies without any hesitation. At first it does it only when my car warms but now it does it in random moments. When it happens my car will only crank but don't start until I let it rest for awhile then it will start up fine sometimes or starts up for a few then does it again.

First thing I checked was spark, wasn't getting any from the spark plug so I assumed like a dumbass it was my cap n rotor, so that was replaced. then my car ran fine for a whole day then it did it again. so i traced it back to my ignition coil, I replaced that and my ignition module(since I was in the area) but did the same thing again the next day.

I also check for fuel.

right now I'm ranning out of option and gonna test my iginiton relay in the morning. Just want more insites if I could of overlooked any other things.

Thank you!

Coolant temp sensor maybe....

It does sound like the cts. The one for the ecu not the gauge.

Mine is a 1990 and had the same problem, only it had a low idle and upon giving it gas it would die. Depending on temperature outside and weather, the difference in amount of times it would die. I fixed the problem first by adjusting the idle air control valve. That did it for me, took me after 3 years to find it. I know now that having a clogged cat and burnt plugs, crappy fuel injectors, clogged FPR inlet(fuelpressureregulator) and leaking valve cover gasket was making the ilde crash down to zero. So I would advise you to check all these that I've stated. Now my engine runs smoother and more powerful than ever. oH! And don't forget to clean the carburetor! Gave me a great boost in power! Good luck!

Throttle body* NOT CARBURETOR.

Clean throttle body with carb cleaner is what I meant!

Maybe fuel pump going out

Check all of your engine harness too for damaged plugs/wires

my s14 was doing the same and had really low idle to the point where it would die. found out it was a bad maf so i replaced and all is good

Changed my ECT sensor, so far its doing good.
if same problem occur I'll be looking more into my dizzy or actually gonna go lookd deep into my fuel, to see if I'm getting constent pressure going.

Thanks for the help guys!
