Re: Another no start for 92 3.1
Since the fuel pressure seems adequate, is fuel getting to the cylinders? If you manually apply fuel or a little starting fluid, does the engine fire?
If administering fuel or starting fluid produces results, are the INJ1 and INJ2 fuses intact? Is the 12VDC supply present at the injectors? What are the DC resistances of all six injectors? If one is below the 12Ω threshold it may be preventing any of them from operating (opening). With the injectors unplugged, is the ECM grounding the injectors correctly?
