well now we are cooking...so pin 12 should be getting power? Is that 12v switched or constant 12v


something else we noticed, with the new harness there is a purple I believe, marked crank, we got nothing from that wire, maybe its a signal wire, not sure, but I do know, we got nothing power or ground wise from it regardless of key position.




The fuel pump was working from the first attempt at a start (even with the bad pedal sensors). We heard it come on each time, checked for pressure, its there, smell of fuel always there for a few minutes after cranking.

purple crank wire usually goes to the starter solenoid if you hooked up the starter relay setup in the harness. I normally use the factory starter wire.
