Ok here are my numbers at the harness, just checked them today.......

This is the harness setup (hard to tell colors), but this is the order and Im sure blue is last.... Gray / Brown/ Blue (Note the "blue" wire is the one closest to the driver side front tire....the one on the end of the harness the other end doesnt have a pin its 4 prong, 3 pins used)

In run engine off.... 2.03V / 1.30V / 0V

Running.... 2.30V / 10.98V / 7.03

What do you think...PCM problem?
