i got the ccrm powered up,alternator is wired in.here's the questions:

1.do i have to power up the IMRC control?

2.i ran a continuity test on pins76,77,103,51 and 24 for the grounds..they all led to one wire in the left of the engine compartment which i grounded.does this make sense?5 ground going to one ?or are there more?

3.how do i power up the fuel pump in my 90?i have power to the fuel pump relay in the 98 harness.where to from there?

I sent you the wiring for the IMRCs. The Grounds specified in the pinout all go to one large ground wire that normally runs to the fender skirt, then to the negative battery post. The PCM case ground mounts to the metal behind the kick panel where the original one was of coarse.

Sounds like the PATS is not turned off. The is the exact symtom! Send the Chip to Chris Johnson at JMS, he can make sure it is cut off.
