Problems I have a 1991 wrangler I am having tons of problems. first it would not start up right away and then it would run for awhile a just cut off out of the blue. I took it to the shop and the guy can't figure it out. He said i need to replace the computer because the reading were all going crazy. I did not know ther was a computer. After he replaces the computer he said he would know better what is going on. Has anyone one else had this much problems with their jeep.I am ready to give up and sell it.

Yes, it has a computer. Have him clear the codes and then begin again. while working, he is likely setting nonsense codes by connecting/disconnecting various sensors.By now, he's likely reading every code in the book. Before changing the computer, he needs to check all grounds etc. bad signals going in will influence what the computer reads and stores. If any of the people you know have a shop they recommend, you might consider using them instead. It sounds a bit like the tech working on your vehicle is lost, or you are not understanding what he is telling you. Computers can go bad, but more often than not it turns out to be a problem elsewhere.

1991 jeep wrangler new motor cutting out and backfireing and acts like it doesnt want to run? what could be wrong ? Fuel is getting to the motor! when it backfires there is a small cloud of black coming...


if it's been running less than a half an hour, it's possible that the lifters haven't filled up to pressure yet; it has to idle a while to stabilize. if it's not that, then look at your ignition timing and your firing order.

My van won't start, iv e check the fuel filter, it is fine. I've replaced the distributor, and yet it still cranks but will not turnover? It is getting gasoline


Try pouring fuel into injectors if it runs and then cuts off it is probably your fuel pump that is bad. sometimes it will run fine for awhile after you prime it but then the problem will come back. So i would take it to a shop right away if it starts that way if it stops running again you will have avoided a heffty tow bill.

Hard starting when cold ( engine cranks normally )


see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

1991 Jeep Fuel Control Issue


Hey Mudkicker,

Who ever thought of putting an electric fuel pump inside a tank of gas........

Check your other gauges for accuracy. They do that when a ground is loose.

Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.

Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.

Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

Comment me back
Mike.

1991 Plymouth Acclaim stalls


One of the more common problems with the 2.5L & 2.2L engines that suffered the symptoms your describing, such as, starts & runs good, then at any given time would just quit, not start, but after sitting a while, or by the time the mechanic gets to it, it starts right up, or you sit on the side of the road for 20 min. or half hour then away it goes for a while longer, then quits again down the road. There is a pick-up plate under the distributor cap & rotor, with the wiring plug coming from it. 90% of the time, it's defective, and cuts out especially, but not limited to, more often when weather is hot.
