Similar to a problem i just recently had. Check, Fuel pump, fuel filter and o2 sensor.

I finally got my mj running right. :wrench: (fuel pump, sending unit and o2 sensor, don't ask :doh: :wall: ) I have a Stock 86 mj with a 2.5 engine and a 4 speed transmission. What upgrades are recommended. It will be a hunting and fishing and working truck. No major mudding or flexing.

It turn out to be a combination of O2 sensor and fuel pump. Thanks for the the help

Filter was the first thing changed.

What tanks will fit? can i use a later model MJ tank? one with an electric fuel pump and change the pump?

What is the purpose od the pan in the tank. I am having trouble with the fuel pump sending unit. (1986 mj 2.5 TBI) could i change to an XJ tank and sending unit and just use an mj pump?

I have a 1986 Jeep Comanche Custom, been having random dying issues. while waiting for parts i dropped the tank to clean it and looked inside it. I pulled the fuel pump sending unit and noticed a few problems. i the screen was zip ties to the pump and there was grit and particles in the screen and in the lower section of the pump. I also noticed that the electrical connection on the sending unit was loose. if i would have filled it up it would have leaked out of the holes for the connection. Question 1. Where can i get another sending unit? Question 2. If i can find one, how can i modify one? Question 3. Can i swap tanks with an similar year XJ? Question 4. What is the best way to clean it?

You will need a speedometer cable for an 88-90 XJ or MJ. If the cluster came from a vehicle with a different engine than yours, you may also have to calibrate the tachometer. If i swap the Speed-o-meter with the current will that be good.

does the 86 2.5 have an IAC? if so where is it located at?

I just got a gauge cluster for a 1989 jeep comanche Eliminator. What will i have to do to install it in a 1986 comanche?

I found a SWB bed and a tail gate at The U-Auto-Pull-It in Monroe, La. The bed stripped i think is about $150

it sputters while in gear, and acts like it is flooding out if i press on the gas (while in gear). if i take it out of gear and press on the gas it does ok for a few more second and start to sputter and die

I am not sure what the problem is. it will run for about a mile and then dies. it will re-start with no problem immediately after it dies. I can figure out why it dies. I was thinkin it may be in the computer, so was thinking about eliminating that.

What about the electronics and the fuel pump?

I have an 86 2.5 4 cylinder with a throttle body on it. After talking to a friend about the trouble i have been having i have the following question. Can an engine with throttle body be swapped to run with a carberator? If so, how hard is it?
