Hello, I’m new to this thread and am currently living in Musella Ga. I work as a heavy duty diesel tech but spend most of my free time turning wrenches on my own stuff. Back in December of last year I hit a deer in my 1990 Ranger shortbed with 2.3 and 5 speed. After installing a new front clip and repairing the body damage I found that the truck had a no spark issue.
I checked everything, I have power to the icm and both coils. Ground to the icm shows 8.5 volts instead of the usual 10-12 and I don’t know if this is problematic. However, my main issue is that I can’t get a good signal from my crank sensor. From what I’ve read the signal should go from 11-12 and then drop to 0 rapidly while the engine turns over.
Strangely I get a constant .25 volts from the crank sensor wire that feeds into the top of the icm and .52 volts at the CID wire. I replaced both the crank sensor and the harmonic balancer and this did not fix my issue. At this point I suspect a continuity issue within the harness but I’ve narrowed it down to either that or the icm. Any help would be appreciated.
