So why are you bumping?

What else have you done to resolve your issue?

What other testing have you performed?

Have you had a chance to compare another car?

You will need to study the wiring diagrams, make sure you have proper power and grounds to the DME. You than may need to disconnect the cam and crank sensors then measure the reference at the DME connector.

You may then need to disconnect the DME connector when the sensors are unplugged and measure the resistance between connections and to ground to see if the harness is pinched somewhere?

Then you may need to remove the pin(s) for the reference from the DME connection and then measure the reference to see if the DME can actually put out the reference.

You may also need to check to see if have had water in the DME box and any corrosion.

Otherwise put a new DME in the car and hope is solves your problem??
