Hi I have an 87 Comanche 4X4 I6.
Since almost 2 mounts my Jeep is very hard to start especially in the morning. (After the first start of the day usually the Jeep is fine.)
The engine is cranking but doesn't want to start. Sometimes it takes 2 or 3 attempts of 15-20 seconds each before it starts. Last week I changed the plugs, wires, cap and rotor and I still have the problem.
This morning I tried to start it but the battery died before it started. So I had it towed to the garage. They put the charger on the battery and it started right away. The guy put water on the wires and near the computer, verified the fire that was going to the cap and the pressure of the gas (38psi when starting the pump and 33psi when engine is working) He told me about the crankshaft positioning sensor (or crank angle sensor) but he's 60% sure it's that.
The guy said that usually sensors would not have intermittent problems.
I checked the Haynes manual and I found nothing.
Can someone help me with that? Or had that problem before?
Thanks a lot
