6-bolt, car suddenly wont start

[ilikespeeding]

Ok, so my friend and I get back from a test drive. The car is strong the whole time. She pulls hard and has a nice idle all the way into the driveway. I stop the car, count to 45 and turn her off. We wait about 45 minutes and go back to test again and it wont start. I dont even know what to check. I've already checked all the electrical connections. I am getting fuel and I am getting spark. The timing belt still has tension. She doesnt hesitate to spin over and there aren't any noises, just no fire. So, it would have to be timing right? I tried moving the CAS back and forth, no start still. I tried removing the sparkplugs and putting a rag into the tube and turning over, all of the cylinders had enough compression to blow the rags out, which should be enough to start the motor. I'm very very confused.

EDIT: This is my 95 Talon which has the 6bolt swap, ECU+, 2.5 exhaust, 2.3 stroker, ect.

Hey, which head/intake configuration is your 6 bolt swap? I know a 1G head will require much stretching of the 2G wiring harness.

Check your coil plug connector.
Check the Crank Angle Sensor connector.

Best of luck.

Any CEL's? Do you have a datalogger? If you have a logger what's your coolant temp? If your coolant temp is clearly wrong (say it's 80 degrees out and the logger says -70 then swap out your ECT)

Would the CTS keep the car from starting or wouldn't it just run like shit? Im running the 1G head with a ghetto rigged CAS conversion. I didn't do the swap, I've spent 90% of my time fixing stupid stuff that people have done to this car, like running 25 psi on a 14b with 550 cc injectors on the stock intercooler.

EDIT: car has no crank sensor.

Anyone else got any ideas?

Ok, so the car runs again. Kinda. I checked the CTS with my ECU+, it read 78 deg F.

If I hit the gas any above idle, it backfires and stalls. Fuel pressure is fine, plugs are good, firing order is good. Im thinking I have a dead coil. I can pull out two of the plug wires and the idle stays the same. I forgot to check if they were on the same coil.

Check fuses, there the most likly to go and cheapest and easiest to replace. Just throwin it out there. Also sorry to here that. I hate my dsm's when that happens and love them when there at top performance.

Also it sounds like it is your coil pack. Also could be transitor plug but since its only 2 misfires I dont think it would be your problem.

Do you know anyone with another dms??? You could swap the coil packs out. That what i did when mine went bad.

I own a 90 GSX. I might have to try that if they bolt up.

 

[talon4lifetsi]

They are different from the 2g's if you didnt already try it.

Damn. I def dont have spares.
