I have a 1989 Ford Mustang LX 2.3. It starts and runs for about 1 second, then dies. If I pump the accelerator as fast as possible while cranking, and release the key while still pumping the accelerator, it runs for about 2 seconds at a VERY rough and low idle, then dies. I have replaced plugs, wires, injectors, cap and rotor, tfi module, starter solenoid, fuel pressure regulator, fuel tank, fuel pump, fuel filter and the IAC. I have tested to see if I have spark, and I have a very strong blue ark, I have tested fuel, and have fuel pressure, and I have also tested oxygen, which I do have with no vacuum leaks. Please help, I'm pulling my hair out on this one. I have work in the morning, but when I get home, I'll post a video of it all in hopes that it will help solve this. Thanks guys for all the help!
