Would a p2138 code prevent the engine from running? Put a scanner on my car and it came up with the p2138 code ( throttle position sensor) and I didn't know if that would not allow the motor to get spark. Or run. Some say yes some say no.....my harness apparently was wired for a truck pedal and I have a vette pedal. I've been told they are pinned differently. So some wire moving is in my future but would that prevent spark? I'm hot to the coil packs connector and coils down I am not.
Key on the butterfly moves on my TB and I have 12v at ECM bat, fuel pump and 12v source.
Anyone?

No, should still start, but throttle probably wouldn't work. If it won't start, make sure you have all grounds hooked up and are good and tight. Make sure the injectors have power, and make sure you don't loose power while cranking, depending what you have your harness powered up by, some circuits will loose power. If that all checks out, make sure your injectors are not stuck.

No spark on all eight coils? Double check your grounds, you have power to the coils and the PCM sends a ground to control them. If that's good, could be in the wiring harness, bad wire in the crank sensor wiring. Does your scanner show live data? If so, are you showing any RPM while cranking?

A little confused. What light blue wire are you talking about? The ignition power should be pink wires, are you sure you're checking the right wires?
