Thanks, I’ll go check your link out, since tge new doors also have power mirrors. We do still have the old doors. I found a pretty good reference (https://oljeep.com/gw/elec/cherokee/91076b24.pdf) and it matches what we have for the most part. Now i just need to figure out a couple colors that...

We swapped 2001 doors onto our ‘89 Laredo. Original had power windows and locks, as do the new 2001 doors. The new doors also have power mirrors. Anyone have a reference for the original harness wire colors/pin locations (kind of back traced it from the switch block) to marry them up with the...

Yeah, my kid was doubting me. Swore we did it right. I insisted we start from the beginning. Glad we did. It also helped that I sprayed the marks down with brake cleaner, wiped them down, then indexed the notch in the pulley with a white paint marker. Now I have to get him a new muffler...

It’s running! The timing was 180 degrees off after pulling the distributor. Our original problem with no fuel pump and no spark was the PCM. Now to clean up the wiring harness. My son was doing a happy dance of disbelief when it started. He wants to get back to driving his truck. I appreciate...

I do have a PB subscription. I’m doing it from an iPad. I posted one photo from PB, not sure how I did it. I’m certain it’s a timing issue we’re having now. I used a bore light to see the #1 cylinder reach the top of its compression cycle, but I can’t see any markings on the balancer to make...

The muffler wasn’t rusty at all. I was pretty shocked. It split it at the seam. I can’t get the pic link to work.

Let me see if I can fix it and post the proper link.

https://photobucket.com/u/rhdimel/p/2bf36aa5-3e5b-4452-9925-426bbee844cf Have had a crank, no start for a few Months. Finally got spark after changing the PCM. Cranked and still didn’t start. Verified spark and fuel, so hit it with some starting fluid. Cranked, got a backfire that grenaded the...

Yeah, we actually did remove the distributor. We indexed it based on Cruiser’s info, but I’m not guaranteeing it was done correctly. The sheer pin is a good call, I’ll have to take a look. Thanks for the continued information. I appreciate y’all.

The latch relay and all of the relays are working. The pink wires show 12v since we swapped ECU. I tried starting fluid and it backfired at the exhaust and literally blew the muffler apart. Split it like a beer can. If he cranks it even without starter fluid, it sputters and backfires. It’s a...

Still not starting. Have spark (from coil and checked each plug wire), have fuel (40 PSI and each of the injectors looks to be firing with a noid light). Any thoughts?

It was under the coolant tank.

My son found a splice that was corroded, and cut it out. He soldered it and put heat shrink on it. That solved the fuel pump issue. Now it primes as it should. So, we have spark and the fuel pump is working. He tried cranking it, but still didn’t start. Not sure how long he cranked it, I’m...

It’s a MasterPro reman computer. The one that came out of it was also a reman. Looks like it was a MasterPro too, based on the labeling. So, we traced wires, tried cranking it several times the other night. I tried direct wiring the fuel pump to see if we could get it to start. It didn’t...

We’e redone every splice we could find. I have the entire harness pulled out of the split loom right now so I can check everything. It’s killing me because it’s my kid’s daily driver and it’s been stuck in the garage not running for three months. Going to have to just keep probing everything I...

My D1 pins are a little different than the pic. I have connections in 4, 5 and 6. My diagram says 4 is the anti-lock module, 5 is battery and 6 is blank on the diagram. I jumped 5 and 6, didn’t do anything. If I pull the orange wire off the relay and run it direct to battery, fuel pump runs...

I have an FSM. That thing has been invaluable. I’ll take a look at those ports, and I’ll try another relay. I should have tried a different relay. I should have tried a different relay first off.

I swapped PCM and now I get spark. The relay cycles as it should on power up. The fuel pump relay clicks but the fuel pump isn’t priming. If I run direct power to the pump, it kicks on, but not through the relay. I’m only getting 7V at the pump, and that’s after bypassing the ballast resistor...

Some background- 89 Laredo with an A/T has crank/no start. The fuel pump doesn’t prime and there ‘s no spark. It’s killing me because it’s my kid’s daily and we haven’t been able to get it started since January. I think it started when he was trying to trace some wiring for the A/C. Not sure if...

I pulled the third relay. I pulled the split loom off to check the wires. The green wire with the heat shrink was one of our repairs. The insulation was broken, so we cut the bad section out, soldered it and put heat shrink over it. I did some double checking on the pax side relays. If i put...
