We never figured out how this interface worked on the '86, so we went around it.

Fore those who do not know ED here is an intrduction. He has been around for a long time. He is the discoveror of the graveyard.

What I found was there is a oil pressure sensor on input on the 89 and earlier cars. If you do not get oil pressure, you get no fuel pressure and the injectors do not fire. In the 90 and later it looks for a tach signal from the dis module. Took me 2 years to finally figure this out. I ran a wire to the oil pressure sensor and it worked.
