I am in research and testing mode. Thought I'd drop this here for some ideas.
1988 4.0 auto. Has been running pretty good lately. Blew an upper radiator hose on the last leg of a road trip. No issues during the trip. Pulled over, changed the hose, refilled coolant. Started right up, idled a bit low but was running. Went for a test run and it shut off within about a block then would crank but not start. Towed it home.
Oil and coolant look good. Would not fire with starter fluid and there is fuel at the shrader valve. Wiggles, unplugged and replugged MAP CPS ant TPS. No obvious damage. Pulled a plug, looks clean and confirmed no spark.
Coolant temp sensor (lower one in block on driver side) crumbled in my hand, but I don't think that would stop spark. All others appear secure and intact. None are very old.
I am going out to poke around - please drop ideas or links as I'll be checking back until I get it resolved.
