Electrical gremlins
I have a 2002 2500 24v HO 6 speed 4x4 with a fass fuel pump, upgraded injection pump, and an edge programmer. My problem is a peculiar one. I have a code for no crank reference signal, 5 volt output high, and fuel shut off high. It does start the fuel and temp gauge get a little off at times and just drop to zero then back up to normal spot. What's going on here?
