97 F250 HD with 7.3 psd. I have a constant miss from one of my injectors. How can I trace it out electrically?
I swapped injectors with known good one and still have a miss. Do I need a oscilliscope to trace out the circuit? My high dollar scanner doesnt tell me anything.
Does anyone have a wiring diagram of the harness between the PCM and the injectors? I have looked and looked but to no avail.
Also having a problem with the ignition circuit. I can be driving along or sitting still and everything goes dead, like th key has been shut off. It fires right back up but at 80 MPH it is annoying as it sometimes does it 3 or 4 times in a mile stretch. Any clues? I have swithched the ignition switch and OHMed out the wires and terminals.
