Question about 1989 Jeep Wrangler

1 Answer

I'm dealing with an 1989 jeep wrangler with a 2.5L gas engine that suddenly died when the guy at the inspection station revved it a bit hard. I've checked spark and fuel, so my next guess is timing. could the revving have made the timing chain jump a sprocket or two? where are the timing marks, and is the advance/****** set by twisting the distributor?

1989 wrangler 4.2 litre engine wont idle


my 1989 jeep wrangler would not idle and come to find out it was a little filter cloth inside the fuel tank that was on the end of the pickup tube going to the fuel filter. It was clogged up and when the engine was started it would just suck in and cut off fuel flow. My mechanic removed the filter cloth from the tube and the jeep runs great. It really does not need to be there because the fuel line has a filter on it. I hope this helps , I know for me it was very frustrating trying to figure this problem out.

1993 Jeep Wrangler, all of a sudden when started first thing high rev. then drops and dies without foot on the accelerator, Manual trans. What could this be.....


I suspect your Idle air control motor - typically mounted on the throttle body fuel injection models. This is not something you would typically have the right scanner to test, but your local shop should be able to test it quickly - meaning it is not an involved exam to see if it's bad. However, it IS an easy fix and if you have basic mechanical skills you should be able to change it yourself. You should be able to keep the engine running if you keep your foot on the gas lightly at all stops, but be careful not to push too hard on the gas - the engine is stronger than the brakes!! I would suggest having it towed to the shop unless your mechanic makes house calls!!

1989 jeep wrangler starts jumping and backfiring


Start with the basics...meaning check the spark plug wires and spark plugs. While under the hood, inspect all hoses for a vacuum leak(s). Then turn the ignition key on-off-on-off- on...leave in the on position and write down the number of flashes the check engine light indicates....2 flashes = #2....pause.....3 flashes = #3.
Let start from here. Are you able to perform engine repairs or diagnostics???

1998 jeep wrangler starting issues


Hi Dava224 i had the same problem with my 1989 CJ. when it was cold out i would pump the gas pedal 3-4 times before turning the ignition. it puts a small amount of fuel in the motor without stalling it out. it wont start as hard. another good idea is to keep some fuel stabalizer in the tank everytime you fill up. hope this helps

Jeep shudders and brake lights flicker as I turn ignition off.


It sounds like the engine is diesiling -- this is usually caused by incorrect ignition timing and/or buildup of carbon on the pistons/valves. Also, lower octane gas can contribute to this.

Sounds like it needs a tune-up.

Startin and runnin problems


Most common failure is crank sensor. Before running out and buying one, I strongly recommend that you do some further testing. Any decent manual has instructions for testing systems. Also: test both running and after it dies. (while running everything may check out as good) If you have spark when not running, check fuel filter as well!

89 wrangler get warm won't idle the takes along time to restart


These jeeps are carbeurated, with heavy emissions systems forced down the throats of Jeep. There are insane Vacuum systems that are too complex to deal with. What I did, (I have the 4.2L) was go out and purchase the Weber kit. I am not selling the part for them, I am actually a happy owner. Mine would die every time I came to a stop. I swapped out the junk and popped in the Weber. I have had no carb problems what so ever. I even eliminated the messy vacuum system! I payed about 200 bucks on Ebay, but from Weber direct they cost around 300. Good luck!
