Why would My 03 Hummer sometimes cranks over but doesn’t start?
03 Hummer H2, 130k miles, No codes.
It only started doing this after a cheap set of injectors were installed. Since then I have changed to high quality injectors, coils, plugs, wires, fuel relay, fuel filter, fuel pump, fuel pressure regulator, camshaft positioning sensor, engine coolant temp sensor.
I was going to change the crankshaft position sensor next. But would like your opinion.
