DME relay, then speed and reference sensors and the DME. I assume the tach does not bounce when you crank the car.

Thanks Doc,
No tack bounce. How do I identify the dme relay? Is the dme relay located with the other relays above the fuse box?

If it is an early 85, then it is under the dash on the top row of relays. Black square tall relay, also called the fuel pump relay.
