Hello all my name is: Maurice
I have a: 1993 3000GT base model
It has the following issue: Crank but no start. I have replaced the following items with new ones: the Camshaft sensor, Crankshaft sensor, spark plugs, ignition coils, new MFI unit, Mass airflow sensor, PTU, new battery, and new fuel filter. I have confirmed gas flow when cranking. It seems as if the injectors are not opening despite getting 12v (not sure if the CPU is sending ground pluses to the injectors). Also sent CPU to repair shop where several capacitors were replaced. The timing is on point, and all primary grounds are in place. I don’t know what needs to be checked next. Any assistance will be appreciated.
ECU is a possibility !
Thank you for responding to my request. I thought that repairing the ECU ruled out any issues with it. It sounds like you’re saying that despite the ECU repair it could still be defective in some way. Is that correct?
I had that problem with my GTO a few years ago. It was ECU.
Thank you. I’ve ordered a used replacement ECU. I hope that does it.
Just wanted to provide an update and say thanks for your input. I was able to start the car with the replacement used ECU. Problem solved!
