The saga continues. New BCM seems to have solved all the issues…except the ones I may have created trying to troubleshoot. It now cranks…most of the time. When it doesn’t, I can wiggle the crank relay and usually get it to work. Cranked and ran a minute before shutting off and trying again. All was good till it cranked and wouldn’t start. Noticed I didn’t hear the fuel pump. Checked the fuse and relay and cranked again and it ran…till it quit. Fuel pump again. Wiggled it a bit and got it going again and while it was running, pushed down on the fuel pump relay slightly and felt it open…then close again. During this period of cranking and quitting etc, I still had to wiggle the crank relay occasionally.
Done for the night, but time to check fuse box plugs and such and grounds. Everything has been plugged and unplugged so much during this troubleshooting that something is probably loose.
