car cranks no start mechanic forum members needed - 3000GT/Stealth International Message Center

ok I have a 96 eclipse GST 16g, I know this isnt a 3s but the dsm forums suck and ive been on here for a couple of years.
the car cranks and wants to start. If I spray carb cleaner in the intake mani it will run for 10-15 seconds and starts.
so far I have replaced
fuel fliter, pump, fuel regulator, plugs, I have checked the injectors for resistance, the pump relay,coils, wires and ive checked the grounds
things I think it could be are
coolant temp sensor
cam sensor
crank sensor
ecu
My thoughts were if the car starts with carb cleaner if it was a sensor or ecu problem the car wouldnt start and run at all. Im lost with this car any help would be great ive done a alot of searching.

Try pulling the injectors out and have someone crank the engine over a few times to see if they are spraying fuel out (keep them away from our face). Also check to make sure that the timing is fine. One more thing I can think of right at this moment is the crank or cam sensors try to get good one from a friend or test the existing one. Last few things, just check for small mistakes are the spark plug wires in order, pull the plugs out and see what they look like after you tried cranking it a couple times.

Is the car cranking easily or does it seem out of timing and it pauses after a few cranks?

car cranks smooth and runs with carb cleaner so I think its fuel related, the plugs are dry and have spark. I'm gona buy a crank and cam sensor and install. I will post results if anyone else has any ideas please post, thanks for the input I'm going to pull the rail and see if the injectors are spraying.

ECU wont spark without crank/cam signals.

Have you checked to see if you have power at the injectors?
Checked to see if the fuel pump is running ?

Check to make sure all your grounds are good. I had a problem with a honda like that and it was my grounds.
