So I am finally getting my GT350 Put back together after 10 years apart and I can't get it to start, looking for some advice. The engine turns over and will run on an alternate fuel source but will not off of the factory fuel system. After running through diagnostics on it I have found the injectors will not fire, the have voltage but no fire signal from the ecm. Fuel pressure is good at 38. I have tested all three grounds and power circuits at the cement which are good and tried two other known good ecm's and still have nothing. Any suggestions? Thanks in advance for the help!
