Greetings Sir or Madam and welcome to JA! I will do my very best to assist you with your problem.
Is the vehicle getting activation on the fuel pump. Do you have fuel pressure making it to the injectors and how did you check for injector pulse?
Customer: replied 3 years ago.
The Fuel pump runs and builds pressure, i took the fuel line off at the injector bar and im getting good pressure, i tested the pulse with a noid light at all 4 injectors
Expert:  Mike V. replied 3 years ago.
Good deal! Any security system on this? I would check for a chip in the key and a security light and make sure they are acting normally

Do you have a test light or voltmeter so we can check the harness for power and ground?
Did the noid light come on and just not p[ulse?

I see that, does the noid light com on when you plug it in and just not flash?

Your Answers Didnt Really Do Me Any Good ( ill Accept It Any Way and figure my problem out on my own ) THANKS ANYWAY)
Expert:  Mike V. replied 3 years ago.
Well, if the noid light is lighting and not flashing,then you know you have power and ground. No light then no power or ground to the injectors. Check the black/red wire for power. Ground comes from the ecm. If you have power and no signal, inspect the crank position sensor as it may not be sending signal. No power, then you need to trace the wires back to the ignition main relay and check fuses. I suspect this is where the problem is going to be because it will run fine on starting fluid.
Sorry about all the questions but diagnostics is not a fast here is your answer kind of job. It is methodical and usually takes several steps.
Thanks for the accept although I feel I didn't help and we drop out in the middle of this.
