ICV seems to be working but not sure if that would stop it from starting. Maybe a little ruff. Have a new DME relay. But as I did some searches I ran across a post from LORENfb stating the following must occur. 1)30 pin always has power. 2)86 & 87 pins have power when key is on. 3) 87b has power when engine is cranking. In checking mine I found everything has power with key on except 85b (30,85,86,87,87b all have power with key on). Only 30 and 87b have power when cranking.The question is does that sound correct or do I have it wired wrong? This is a 88 3.2 in a 70T. After years of being apart (including the wiring) it's going back together. Any thoughts would be appreciated.

85b gets its ground signal from pin 20 of the DME ECM when cranking or running.
This causes 87b to provide 12V to the FP.
Sounds like inadequate fuel pressure - bad pump.
