This is a npr hd with a 6 litter gmc engine and it has no stored codes but flashed po300 a couple of times. It was running fine and I shut it off and now it wont start. I tried spray start nothing so I replaced the crankshaft sensor and still nothing I checked the three wire plug with the ignition turned on and all three wires had 12 volts I was told one should be a ground steve
