Full disclosure, I am not the best with a voltmeter, how I should be able to test for voltage and continuity.

However, is there general consensus that because the car runs with a jumper in place the cps is OK?

IKE84 states,
"]This may actually be due to your ignition tumbler. If your dme is dry and all other systems are working properly, but your relay is not energizing while starting, I would look at the ignition wiring and tumbler.

I noticed that when I put the jumper in place, the fuel pump fires up before I turn the key. Does this Support Ikes thoughts?

When you guys refer to the DME, is that the box in the trunk behind the carpet? When my immobilizer was rained on I sent the board from under the seat and the what I thought was the CPU to folks in Florida.

jfp states; I would be checking the CPS signal at the DME plug, which takes the entire harness into consideration. I feel clueless, is this the box behind the carpet and do I just need to become more learned of the wiring diagram in the Bentley book?

blues62, I live about 100 miles west of you so maybe one day we can meet F2F.

Anyhew fellas, any more guidance is welcomed.
