My lift pump (Raptor 100) is not coming on...the idiot light came on just a mile away from my home so pulled in the driveway to check it out. Not hearing the pump cycle when I bump start. Did not see voltage on yellow wire or illuminate a test probe light during 25 sec bump. Truck starts and idles (from little lift pump in vp44?).
I'd like to test continuity from the ECM plug to the lift pump but don't know what pin hole is the right one? Or any other suggestions?
Really appreciate some help!
Thanks,
