Yes we did get a chance to look through the link. There's a lot there to digest if I'm going to need to measure individual wires and their respective voltages.

I thank you for the provided link. So far we've narrowed it down to the fact that we are getting sufficient 12 volts into the distributor but nothing coming out! We changed the coilpack, the distributor, the cap and wires ... we seem to be getting a pulse from the crank sensor ... a pulse is all we need ... I think as I said it almost seems like we need to await the proper alignment of heavenly bodies then vroom vrrooom ...

Cheers,

PS. Help

Yeah, today I woke up thinking that my favorite band died in 1994.

RIP Nirvana

Good news is that today I'm playing games! Gonna be fun fun fun, first up is a little card game called Magic the Gathering. There's a new set today! Then my group are meeting for Dungeons& Dragons. Everyone present gets a bonus 2D6* 1000 gp to buy magic items with!

All have a good day,

Cheers,

Good luck, and have a great day.

I received a reply to my want add in the local list:

Can someone confirm this procedure?

I don't think that is correct for a 93/94 ZJ, or any Jeep of those years.

X2. I have a 94 ZJ. Never heard of anything like that. From CF or the dealership. Unlocking the passenger side door or rear hatchback with the will passively disarm alarm. Unhooking battery for 3 minutes resets security. What that guy is explaining in the ad looks like a cross between programming a FOB and turning your ignition 3 consecutive times to check for faults. Wish I was at home; Haynes Repair Manual has this method.

X3. Never heard of that either.

Okay thanks guys, I just didn't want to feel like a dork with a timer.

I'm gonna go through the wiring, see if maybe I can swap in the module that keeps track of the "service vehicle in XXX miles", swap in the module that keeps track of remote keyless entry (up top console) from 93 to 94. (I wonder if I might have to swap in the instrument cluster for odometer as well.)

If I can't get it to fire up by mid-week, I'll talk to my neighbour and see if I can borrow his 93 ZJ to use as a reference vehicle.

let us know how it goes

that method is incorrect, similar method is used on gm chip keys

Okay, I think ... I *think I may have found my problemo. It resolves with a certain lack of ground for my TCM. I described the symptoms to a friendly veteran mechanic (talking with him I could almost feel a calm only attained by many years of steadiness) and he suggested that there was a ground missing somewhere.

I remembered hacking off a ground from the motor to 94 harness. This ground was not present on the 93 harness. The top plug-in is similar in shape but wired differently! I traced the ground wire (I think black and orange stripe) and sure enough the 93 PCM gets it's ground from the top plug. The 94 PCM gets its ground directly from the block. The boys at the dealership must have figured that it was better to get the ground directly from the block.

At any rate, I'm apprehensive to just snip the wire and ground it. I don't want to blow the PCM in fear that any other wires on the top plug are different. From appearances there are more than a few different coloured wires. But, I don't want to swap-out another dash harness ... I did that with my 84 jeep cherokee and well ... yeah, it was rather unpleasant.

So my idea is to cross-reference both plug schematics, from 93 and from 94.

I have to say that I'm excited. I'm reminded of a passage I read in Lord of the Ring, when Frodo is in Rivendell and Gandalf and the Elves have successfully removed the broken shard from the Mordor blade. He awakens feeling renewed, where he was before ill and dying before and upon awakening he is rejuvenated.

Anyhow, now to try and dig up a diagram for the 94 Cherokee.

Ya, I am assuming this book is for the 1993 ZJ? I can't seem to find the 1994 ZJ ...

I'm not sure what year/s that's for.
Go on here, type in the info you need and it should help you. (It's free).>->Jeep Informational Center at Morris 4x4 Center

Thanks, but this online form only provides info for 93.5 to 94. It's like they conveniently ignore the fact that 93 had a completely different transmission and electronic wiring (PCM and beyond). As I was lucky (to be unlucky) in finding a 93.0 ZJ, I am seemingly hooped.

I'm gonna call my dealership again and see if I can pull the different plug wiring info.

Cheerio,

I wish I could be of more help. Good luck, and keep us posted.
