If it's getting fuel, spark and it's cranking but not starting unless it's fed ether could it be an injector(s) issue? I've gone over this car 100 times and can't figure it out. Fuel rail or injector(s) issue maybe? I'm at a loss.. Any intelligent suggestions welcome. Thank you in advance.

 

Sounds like you have a fuel delivery issue. How did you test for fuel pressure?

Did you do any work on the car before you had this problem?

 

Fuel pressure gauge and its bored to max, bigger head, cam, exc.. But that was over 30,000 miles ago and I don't drive it like and idiot and its all still like new

 

Had nitrous to it twice but that was 20k ago

 

Suggest checking whether injectors are firing w/ a noid light, circuit tester, or listening w/ stethoscope.

If no injector action, check wiring and ECM for injector signal output/delivery.

good luck

 

Also check that the injectors are getting electrical power. The injectors always get (+) power & the ECU switches the ground side of the circuit.
