Thanks to both. It's a 1990 and it was between the steering column and the heater/ac unit.

Say, can someone with a 2.5L engine post a photo of under the hood looking down, specifically at the distributor side of the engine and also let me know what year yours is? I am looking for a 1990 to check out how much different mine is than... anyones that might be running. lol

Thanks Wildman. The red triangle is a hazard lights symbol. Did I mention this vehicle is Canadian?

For anyone who is interested, and since I ripped apart my dash to get it, here is what the left cluster has for a shine though skin: I don't see a check engine light, but it's probably the top left or something else that I just don't know. I put little white light symbols beside the ones that have lights in my vehicle ( 2WD )

Oh man... I spent 3 hours in my truck pulling the bezels out and trying to swap bulbs. I was about to post a picture of the shine through. lol.. I guess there is no need now... unless someone wants to see. All ground points are now clean. All ground straps are as they should be but to make sure, I pulled them, cleaned and scraped them, and put them back together. I like the idea of it being a timing issue as it's one of the only things I haven't tried.

This might be an odd one but where is the ECU located on the Comanche?

The hoses are in fantastic shape (I just replaced any that were even close to suspect). I also made damn sure I put them in the right place. I will be scraping the paint off of the ground cable and checking the other end. Thanks! Say, does anyone know where the ECU is on this thing??

Where is the IAC located? The CPS checks out and I will double check the TPS, just to make sure I did it right.

Thank you. I sent him a pleading message. I can only hope. I did notice something new when I was trying to start the truck. The power cut out every 3 or 4 seconds of cranking. The battery is pretty fresh and has a fresh charge on it. I don't know what it could be. Any ideas? Could this be relative to my other problems?

Well, thank you for the info. I now have a sad heart. No one I know has a DRB-II scanner. I have never seen another 1990 Jeep Comanche with a 2.5L around, let alone one with a computer I can use. Well, I can't wait to see the burnt out Check Engine bulb. I suppose that means it's been on for a while, eh?

Thanks to all... but nothing yet. I feel my next step is try to retrieve codes from my ECM. I have found a connector over the passenger side wheel well under the hood. It has 2 yellow caps covering the connector pins. I have the picture they show in the Haynes manual and a photo of the caps. It shows to jumper a couple pins and turn the ignition to ON. I did that but I see no Check Engine light. Nothing Flashes The Key ON-Off-ON-Off-On thing doesn't work (it did in my previous Chrysler type vehicles). Furthermore, I cannot find a Check Engine Light at all on my dash. Being a 1990, there is NO OBD-II connector. Is the 1990 the only Jeep without a way to manually retrieve codes?? Also, where would my check engine light be?? Maybe the bulb is burnt out. lol This is the photo of the Yellow covers covering the following photo. This is what is under those yellow covers. Please note that it mentions a diagnostic method for the V6 engine but not for my 2.5L 4cyl.

Greetings. I have a 1990 Comanche with a 2.5L engine and a 5 speed manual tranny. It is VERY hard to start. When it does start, it runs rough and I have to feather the gas to keep it going. When it warms up, it's drivable but if I give it just a little with the accelerator, it bogs and hesitates. This is driving me nuts. Here is what I have done and checked so far: I changed the fuel filter Replaced the fuel pump Tested fuel pressure (a-ok) Tested the MAP sensor (a-ok) checked distributor for proper placement and position. Changed distributor cap and rotor Changed Spark plug wires Changed ignition coil Had the injector cleaned Tested compression (100%) Changed air filter ... I'm sure I am missing a lot here but any help would be good help Much thanks!
