Question about 1993 Jeep Wrangler

1 Answer

Still no fire

I have replaced the crank position sensor, alternator, ignition coil, distributor cap and rotor button on my '93 jeep wrangler 2.5 and still can't get a plug to fire. It doesn't have an ignition control module, only the powertrain control module. It is flashing a ground fault code in the A/C fan clutch relay, but I do not have an A/C unit or any spot for a relay to the A/C and am not sure if it is picking up a bad ground or what. I recently removed the tub and undercoated the frame, and upon re-assembly, I can't get it to start.

On my 1993 wrangler with a 2 5 if i try to start it it only fires on cylinder 1 and 3 if i shut it off and try again it fires only on 2 and 4 what would cause this


Sounds like a spark plug or distributor problem.... Change out all your spark plugs and check your wires for breaks. Check fuel injectors for build-up.

My jeep is not getting fire what are the possible reasons its not the crankshaft position sensor or the coil.


I think your 2.5 still has a distributor...check for a cracked cap, or cracked rotor...same symptom...hope this helps.

I need answer for truck not firing. On. A 1991. SERRIA 1500 TRUCK 5.0 LITER


Several things can cause this problem, cracked distributor cap, old ignition rotor. Or if you have coil packs, cracked coil pack, ignition control module, crank position sensor, cam position sensor. Coil pack parts and sensors can be checked by autozone, cap and rotor will have corrosion on the rotor, however a small crack in the distributor cap can be next to impossible to see, replacement is usually best option.

My jeep will cranks but won't fire. Have changed distributor cap and rotor, plugs and coil but still won't fire.


Try checking your cam sensor and crank sensor. You can test them with a voltage meter. Many times, the sensors will go before anything else. It may be your distributor itself. Test it as well. If you have a question, please let me know. I am here to help. Thanks for using FixYa. Have a good evening.

My truck was running good when I parked it but now it will not fire, I have replaced the cap, rotor and coil but still not spark. I have fuel at the rail and the engine cranks. What next?


Replace the ignition module,make sure the rotor button is turning,remove the cap,and turn over the engine,if the rotor button is not turning,then,the timing chain is broke.

No Spark


The " FIRE" doesnt come to the coil from any of those things you have changed.......The "fire" comes from the coil TO those items!!!! Good luck, RC

1991 JEEP WRANGLER WONT START


Take the distributor cap have someone crank the car and look if rotor turns, look at rotor conditions, I am sure that you have replaced it, hot wire from positive on the battery to positive on the coil, if car starts after you have a problem on the key, Is it fuel getting to the injectors? after You replaced so many things,if your rotor is not turning when You crank the engine, your timing chain must be defective or timing gear,
