Re: '93 GCherokee 6 Hard Start
Hi Dennis,
My only experience with Chrysler's electronics is with this group,
which the problem ninety nine percent of the time is the Crankcase
Position Sensor, the other one percent being a fuel pump or it's
regulator bleed down. Only one person has wrote back saying it was the
computer it's self.

Re: '93 GCherokee 6 Hard Start
Thanks Bill,
I do have good fuel pressure. Just was hoping there was some absolute test I
could do on the CPS before digging down to change it.

Re: '93 GCherokee 6 Hard Start
D did pass the time by typing:
Hmm. I think that's just a spacer. Hard to say without opening mine up,
but the only sensor in there is the stator and that plate (which I now
understand they call a pulse-ring) Amazing what you can learn from the
service manual. :)
Besides, if your timing was off the ZJ would be pinging/backfiring/etc.
I don't believe the distributor is your problem. That temperature
sensor fault is the most likely cause. If your Jeep reads it as overheated
it will not start or it will go into limp-home mode.
You need to test it with an ohmmeter.
http://members.***.net/wilsond/Fixes...tml#tempmatrix
One other thing... open up the relay center, remove, clean, and
reinstall the ASD relay. ASD = Automatic Shut Down. Give it a
tap with a wrench. The pupose of that relay is to kill your
engine if something goes terribly wrong. If it fails or sticks
your jeep will not get voltage to the coil.
As Bill said, it may be your crankshaft position sensor. Not a cheap
part and not easy to get to. (not impossible, but a real pain)
I'm running out of ideas.
