IMRC Woes

My IMRC is not opening my secondaries and I've tried swapping IMRCs with a junkyard one and another that I bought off a member here. So far no luck. Anything else I can try? Any fuses that affect the IMRC. I really want my extra power. No CEL lights at all.
Help?

Start by using a multimeter to check the plug on the IMRC to make sure that it's getting power.

i would try Throttle position sensor. i had that problem with my IMRC, but i was using a dead 3L TPS on my 3L TB... that's my 2 cents

Do I just test these when the car is idling or reved at 4000rpms?


I'll look at the TPS tomorrow


UPDATE: The TPS seems to be OK. The return signal from the TPS goes from 0.9V to 4.52V as I open the Throttle.
