I looked for my second reply to you could not find it. With the relay out I have a 11.7 volts at post 85 but when I put the relay in I get voltage reading of.017 with the key in the on position and that does not change when when I turn the key to the crank position, the engine still does not crank with the key.
With the relay out I actually get a positive voltage reading on pin 86 also it isn't much but it is there.

Hello again,

Okay, with the relay out there should be 0 Volts at pin 85. Pin 85 is the Ground for the electromagnetic coil and is supplied by the ECM through the purple/white wire. Trace the purple/white wire from pin 85 to the ECM and look for a short to power anywhere along the wire. If none is found then the ECM has an internal short to power in it and will need to be replaced. Get back to us with what you find, please.

Thanks,
Alex
