I hadn't replaced the DME relay or the fuel pump relay because I found that I wasnt getting the proper voltage to the DME relay Pin 85.
This info is incorrect. Relay pin 85 is a ground, controlled by the DME. It's pin 86 that should be hot, and it should be hot (+12v) at all times. In other words, the DME triggers the relay by grounding pin 85, thereby completing the circuit. Still, if you suspect there is a break in the connection at pin 85, you can run a continuity test- it enters the DME via pin #27 on the DME harness. Hope this helps.
