Ok guys,
I have a 1987 Jeep Comanche 4.0L inline 6 that will crank, start, and then die out seconds later. when i go and try to crank it again after that it won't budge as if the engine is locked up. if i give it 30 minutes or so it will crank, start and do the same process over and over again i have been trying to figure this one out for a month. i have replaced the battery, starter, alternator, fuel filter, air filter, plugs, wires, distributor cap, rotor and button. I'm out of brains to figure this one out. help would be appreciated.
