Hello

Do you have injector pulse voltage, connecting the voltmeter across both injector wires should show fluctuation in voltage when cranking or if your using an injector test light it should flash, have you verified this?

Customer: replied 8 months ago.
No.
Customer: replied 8 months ago.
I will try that!
Expert:  Ted Ritter replied 8 months ago.

Thanks for the prompt reply, waiting to hear back from you, take your time.

Customer: replied 8 months ago.
Using volt meter, I have 12 volts at both terminals. Cranking shows fluctuation.

All right, then the computer is firing the injectors, does it run if you put some gas directly into the intake?

Customer: replied 8 months ago.
Cold start injector is putting gas into intake, it coughs and belches through exhaust but won't run.
Expert:  Ted Ritter replied 8 months ago.

Sounds like there is no fuel or not enough fuel pressure for the injectors to let fuel through, how is the fuel pressure to the fuel rail?

Expert:  Ted Ritter replied 8 months ago.

Was the engine you put in a used one or did someone rebuild it, do you know if it ran before?

Customer: replied 8 months ago.
Engine was professionally rebuilt. I will try a different fuel rail that I have on hand.
Expert:  Ted Ritter replied 8 months ago.

Ok, make sure there is at least 38psi while cranking.

Customer: replied 8 months ago.
OK thank you.
