Put a scanner on it, check live engine data, need something to go on? Check if the system is rich or lean. What is the fuel pressure spec?

Put a code reader on it got nothing. How do I check how rich or lean? Fuel pessure is supposed to b 120 and up, when it was checked was low, so I started there with changing the filter and pump.

My info says 46--50 psi, key on engine off, for fuel pressure. Do you have an injector pulse?

Use a noid light to see if there is a pulse, engine cranking. At the moment, I can't tell if you have an injector pulse. The computer controls the ground for injectors. If you add a little starter fluid to the intake does it try to hit? There are safety issues with any flammable spray. Safety is your responsibility. I usually take the air duct loose from throttle body, open throttle valve, spray just a little, stand back away from engine, have helper crank. If it tries to hit, I think you have a fuel issue.
