Thanks for the heads up on the coil replacement. I knew that I definitely
didn't want to go with the Wells replacement. I haven't had good luck
with those guys. Currently there is a "Screamin Demon" coil in place that
came with a package of supposed upgrades to the ignition system to include
a brass terminaled distributor cap/rotor button and sleeved plug wires. I
don't know what possesses me not to leave well enough alone but there's a
driving force in my soul...

Tell me about it. Driving force in the soul and draining force in the
wallet. :)

Re: This gremlin is still eluding me!
 

Since my last post, I have ruled out the coil, the distributor, and the
PCM. I'm left with a short somewhere in the wiring harness. As the Jeep
refuses to give me back the codes from the PCM and the fuel guage doesn't
register when the key is in on position (yes I'm sure there's gas in
there) where is the most likely spot for the short? Between the ignition
and the PCM or from the main fuse block and the fuel pump or another
unnamed option? Any and all suggestions are appreciated as I am near my
wit's end and have seriously begun to consider the efficacy of military
grade explosives with regards to this particular problem.

To simplify, here's what's been checked so far (I swap the parts one for
one into my wife's JGC and start it up before saying a part is good when
possible or used the multimeter as appropriate).

-Throttle body complete with all attached sensors
-Crank position sensor
-Cam position sensor
-Ignition Coil
-PCM
-Plug Wires
-Main grounds at firewill and near dipstick
-Ignition Switch
-Fuel pump relay, ASD relay
