Comangi

Thanks! Sorry for the wrong forum. I asked Kody first, ha! He's out.

Hey all, so my ECU is fried. I have an '86 5 speed 2.5L comanche. They have an ECU on rock auto, but it says it's for the automatic, the part numbers it lists don't match the one on my ECU. My PN: 8953002099 I've been searching and I've found plenty, but they either look different, or are $400!! Anyone have some insight as to where/how I can get one that I can trust will work? Thanks so much!

so my '86 2.5L broke down a while ago. No fuel, the pump wasn't kicking on when I turn the key to the run position. Looked at the relay, wasn't firing, bridged the power sources in the relay, pump kicked on. Replaced the relay, still doesn't work, i found the ground in that particular relay pigtail is extremely weak. Even with the fuel pump bridged and running, no ignition. so I'm assuming the bad ground effecting the relay is also stopping the ignition from working correctly. I did all of the grounds from the renix tip page, firewall, tail light, dipstick. No help. So i moved on to the c101 connector. I can't find it, there isn't one. Which tells me maybe my '86 isn't 100% '86. Great, so now I have a bad ground, I assume it's somewhere in the loom? I'm considering running a ground wire right to the relay pigtail and seeing if that's my problem. I'm not a big fan of fixing things the "wrong" way. Any ideas? Any input would be great, leads, ideas on where I should check next. I can't find any obvious faults, pinches, cuts, etc in the loom. What am I missing?

One of them is the fuel pump, the one closest to the firewall. Pretty sure the other two are AC compressor and cooling fan clutch? I could be wrong on those two.

Sorry man, but she's their client and her statement contradicts yours. You didn't take pics of the scene? that's accident 101, man. Also, like lots said, you can't expect payment for aftermarket parts. You need to have had the aftermarket value appraised and have it insured by your insurance company before the OTHER company will pay for them. It's a pain, believe me. I also have USAA and they have been nothing but stand-up and honest. Sounds like they are standing behind their client. That being said, I hope the police report clears it all up and they pay, but how can you expect them to pay to fix aftermarket equip? They are only on the hook for replacing stock parts.

What did you glue it to? Looks killer man, I'm going to try this.

Sorry, the only pic i see is your avatar pic. Is there a jeep in this thread? ha, killer build so far man, that jeep looks amazing. Well done.

I've got a '97 column in my '86. Don't know if that helps.

Thanks for the feedback. Eagle: I don't know any of my alignment measurements, I want to know what's going on before I take it to get aligned. Don't want an expensive surprise! Rockfrog: What do I do to diagnose this? Any input on how I figure out if anything is bent? do you think the outer tire wear is not camber, but a toe issue? I'll try to get some front-on pictures of the jeep so you can see how the tires are aligned.

So I know this topic has come up, but I'm 90% sure i don't have a bent axle tube, so I am wondering whats the best way to correct my camber? As you can see, I've got some really bad camber. The tires are pointed inward at the bottom. if the axle was bent, they'd be inward at the top. so what can I do to fix this? As an aside, I was looking around, and I saw that my spring contacts the spindle, what's up with that? Is that normal? Thanks for your help!

Update: The comanche made a 320 mile round trip into the mountains this weekend. The hills were rough, but I only needed 3rd a few times. The jeep did awesome! I got out and back, logging trails, 2 trips up the mountain with 1K+ LBS of wood in the bed, bouncing around the muddy ruts of the trail, then back home. only used 3/4 of a tank! The alignment did a number on the tires, the fronts are almost completely shot now. They were close before. Eagle, above you say if my speedo was at 60, i was doing closer to 70. Are you sure? at some points, I was cruising at close to 70 on the speedo. I can't imagine I was up close to 80 MPH. People were still passing me! All-in-all, the jeep did amazing. Now time to figure out my alignment problems and replace the two front tires!

Thanks for all the tips guys. I'm going to go do some reading. I took it out on the highway again today and stayed in 4th, my issue was WAY WAY better, also the MPG on the highway was better. I guess I'm a dummy and don't know how to drive an old jeep! using 4th was a huge help. Now to go see about spiffing up my motor! I think my biggest problem is that with the mud tires and zero interior (besides seats) the jeep is SO LOUD above 50MPH, that I can't hear the motor. Without a tach, I've got no idea where my RPM are. I guess I was hitting hills in 5th (didn't know any better) and was probably at very low RPM. Once I hit hills in 4th, at what I'm guessing is 2K RPM, it was buzzing along at 60, no problem.

wow, so what gearing would you recommend for 35's? something even bigger?

I was thinking 4.88's. The chart says 4.56's give you a decent RPM in 5th, but that's with a decent motor! 4.88's should do the trick. I hope!

Thanks for the info guys. I'm thinking my newbie a$$ needs to stop hitting hills in 5th gear! So, with the 2.5L, will 35's just be a terrible idea? even with gears?
