Ok so here is the problem, I have a weird intermittent starting problem. All the details first 89 with 2.9 to 4.0 swap 5speed truck. when doing the swap I did not have a m5od to go with the 4.0. But I had a 2000 mile old 2.9 clutch and new starter. So I kept the 2.9 stuff flywheel back. Plan was to find a M5od. Well the clutch slipped and the throwout bearing was toast. soooo
It was time to swap in the 4.0 clutch/flywheel still using the dreaded fm146 Now It cranks for 5+ sec. will cough aka semi backfire and stop the starter. Or it will crank shudder a bit then run like normal. Fuel pressure will hold at around 40psi for over an hour so pump and reg are good. Batt checked out and I only get a volt drop to 11.2 during cranking. I have swapped the wires on the fender solenoid as noted. The motor cranks easy and fast. As I noted this one started after the clutch and starter swap. Anything you guys can think of to test or check ?
