88 Comanche stalling
Hi,
I have a 88 Jeep Comanche, six cylinder, automatic transmission, fuel
injection, 4WD with approximately 88,000 original miles. Up to last week, it
started and ran like a champ. My son (maybe the problem) took it to work one
day last week. When he came out of work, it would start and then die.
Start/Die Start/Die Start/Die. I had it towed to my mechanic. He told me that
it was not getting any pressure from the fuel pump. Installed one and now it
gets 40lbs pressure. Still won't run. He says if he sprays starting fluid into
the intake hose, it will continue to run. After doing this for a a little
while, it would continue to run without the starting fluid. After shutting it
off, and leaving it set for a few minutes, it won't restart without the
starting fluid. He says he is 99% sure it is the computer. I can get one from
the junk yard for $75. When I talked to the guy at the junk yard (a junk yard
that didn't have one ) he said that he'd never sold a computer for a Jeep. He
said they just don't go bad. My mechanic is pretty good, but I'd like to get
some input from you guys before buying the computer. Please ....any ideas??
Thanks.......Ed

Re: 88 Comanche stalling
Hi Ed,
Ninety nine percent of the time it will be the Crank Position
Sensor: http://www.----------.com/woody.jpg It may also be the fuel
check valve that's apart of your fuel regulator sitting on the fuel
rail. If it is you'll be able to prime it by turning the ignition to the
on position without attempting to start the engine and listen for the
pump to shut off automatically, then turn it off and back to on, at
least five times then try to start. if it now starts you've found the
problem. It still could be the brain box.

Re: 88 Comanche stalling
Before changing the computer, first try switching the fuel pump relay.
Had the same problem, which was fixed for 6 euro's.
Standing on the passengers side it is the second form the right.
Try switching it with the most left one which is the A/C Clutch Relay.
It will probably start immediately.
Good Luck,
Rodger from Holland.

Re: 88 Comanche stalling
you're lucky to have a pure amc jeep. I have one, too, an 87 comanche long
bed pioneer that looks and runs like brand new. someone should have
pressure tested the original fuel pump before putting on a new one. I'll
give a look in my factory service manual and see if I find a sympton like
you describe....have you tried cranking it with your foot on the gas pedal??
