First post to the club, but a frequent user of the great advice you guys offer. Having a crank issue with a 91 4.0 Have power, but as soon as I turn the key completely to ignition I hear one click coming from the starter, the starter is trying to engage but then I lose all power and Can not keep trying to crank until I disconnect the battery and the reconnect to have the same thing happen. Things I’ve checked and or replaced: Starter Starter wires Grounds Ignition switch nss (completely replaced) all relays and fuses battery (used multiple different batteries to be sure) battery terminals and negative and positive terminal clamps radio and speakers (checking for shorts) Fuel pump ballast resistor map sensor and probably a few others that I’m forgetting Probably have about 25 hours in to this problem and I’m at a complete loss. Maybe I messed something up along the way so feel free to give any knowledge of common mistakes made during install or my checks along the way. I hope what I’m trying to say is clear and if not I can clarify

Looking for a drivers side switch panel for windows and locks for a MJ/two door Cherokee part #55002135. Updated and Edited 9/8/2018: I purchase the seal from Dzimm and I am still looking to see if anyone is willing to sell the driver's side window and door lock switch panel to me.

I'm new to the site and recently picked up an 86 2.5L with a 5 speed and 4.10 gears. I know its a 4cyl but it just doesn't have the power to make it up some of the hills in town anywhere close to the speed limit. Are there any upgrades (other then motor swaps) that will increase the power and performance? Right now it is fully stock, but I'm planning on putting on a 3" lift and 31s before the winter starts here. I have heard about throttle body swaps and different injectors, but i don't know where to start. Any help would be appreciated.

Hi All, I have a 1990 Jeep Comanche, 2WD 2.5L 4-Cylinder. Manual AX5 transmission. I've done some minor transmission / clutch work on it with plenty of help and support from the forum. Generally, it runs fine (now). But... Recently it's been doing two strange things: Losing power (shutting off) at low speeds, normally when jarred or bumped. It starts right back up when this happens. Most often, this can be seen when it's parked and I start it, then release the parking brake. When the parking brake jolts, the truck loses power. I have to re-start it. Also, on occasion, it loses power at low speeds (parking lots, mostly) often on bumpy terrain. It always starts right back up, but for the moment when the power steering fails, it's no fun. Lurching / losing speed while driving. When driving anywhere from around 30 to 55, it sometimes suddenly slows down a little -- just a mile an hour or two -- but very quickly, sort of lurching a bit. I can normally compensate by pressing the gas pedal down further, then it just sort of evens out. It never gains speed while lurching, only loses speed. And most often right around 40 - 45 mph. It feels like it's either losing power or gas suddenly -- but the truck doesn't shut off of anything. I recently (several weeks ago) lost power completely (truck wouldn't start) and found out that the main battery cable was corroded and much of the insulation had rotted off many of the cables. I got the truck running again with some electrical tape and a new clamp for one of the battery terminals. I imagine the above problems are related to electrical issues, but don't know how to troubleshoot them. The battery cable itself is very complex -- lots of wiring in there going who knows where. I also on occasion have some odd electrical issues -- namely the windshield wipers behaving unexpectedly and the turn signals staying on until fiddled with. Anyone have electrical experience on this or a similar truck? Do these all sound like electrical issues? I'd love any advice, tips, feedback or whatever. Thanks much, this forum has always been a huge help.

Ok guys I'm kinda new to the world of jeeps but I'm looking to get some more power out of my renix 4.0. What are some parts. (Cheap bolt ons) I could get to build more power. I've already made a cold air ram air intake for it. And she's got after market exhaust. What else can I do!? It's got stock injectors I'm going to swap to quadrajets soon. What have you guys done to push more ponies? Thanks guys.
