Hard one :-) climb over remove the cover,slide keeper off the lock fit new barrel and key.

My best guess with what you are saying is you did not "RUN" out of gas but actually had fuel still in your Tank. What happened was one of (3) things.. Your Fuel Filter is clogged (but it would have run sluggish or a hesitation prior to this happening. The 2 Most common problems that more than likely happened is either (A) Fuel Pump/Fuse for the Fuel Pump failed or (B) Crankshaft Sensor has failed.

check your fuel pump

Check the fuses, then the next thing to check is the Freon level. You can get a do it yourself kit at an autoparts store. They are not too expensive. If it is totally out of Freon though, it could be expensive.

code, what does that mean? ahh the computer fear thing, like on all newer cars. you meant does my PCM need to be reprogrammed to use my new pump. NO> ! step one says: for pump) but if you remove the cars battery , some things will forget. like radio stations, or radio password activation codes. i think 98 has no radio codes. no NAV , no idle learn codes and for sure no throttle by wire, re-learn codes.

LEAKING INJECTORS (DO NOT PARK NEAR HOME, PARK IN STREET) fuel that hits the oil pan can run down the exhaust pipe and put fuel on the ground, very very dangerous. all cars. the turbo is the least of worries. on the JEEPS,we do what is called an injector leak down test. its in the FSM how to do so.... and the injector balance test. my answer is , GET IT services, now, and do not park in the garage.

catalytic converter or o2 sensor maybe

sounds like you have a door switch going bad. or ot could be the liftgate switch.

We need more info on just how you damaged the harness plug. If it is just the clip that locks it on to the pcm (the proper name of the computer on a jeep is Powertrain Control Module) simply wrap the unit with a zip tie to lock it in place. pulled tight a cable tie will hold tighter than the plastic clip on the plug,

bad lock, or its jammed some how, the key has to work. replace the lock. or get a lock smith to fix it. Id pull the skins and check it very carefully , even remove it and make sure its not damaged somehow, ice damaged, last winter. and progressed to worse. most damage does that. just to be sure, make sure its not in child safe mode. did you read the operators guide, on that?

I've come across a couple with poor battery connections do the same thing... The EAS/BAS light will turn on and store a pending code when the system detects low battery voltage.

mine did the same, so i had to stop using it
i did read somewhere that there is a way to ground a particular wire to disable (trying to locate that article for you ... i have not tried that yet).

have the battery tested for holding charge and the alternator checked for charge rate as this code indicates low power supply to sensor/s, although it does'nt give a specific sensor it would suggest the power supply is the cause , keep me posted if you wish

dome light bulb is loose in the socket. take off the cap and adjust bulb.

Most probably the crank or cam sensor which is getting bad.Did you get it scanned to see if it has a fajlt code set?

Hello. Security systems (alarms) can cause problems when they become bad. The best thing to do is disconnect the fuse for the alarm. Look in the fuse panel of your car and see which one is for the security system (alarm). Then you can pull out the fuse and it will disarm the security system. Good Luck.

I doubt you will find just the button/switch. You could take the switch apart and see if you can fix it. Or you can replace the whole module. This one is 164.00 MOPAR Air Conditioning Heater Control 55115904AC

This is not much information to go on; but I can ask questions, and you can check. Does this have the 4.0? Does it have a chipped ignition key? Does it have a security system? I am going to guess you have recently cut a new key? I am not sure, but think you have a key with a chip in it. If you switched keys, you will need to have the key programmed. If you have the old key, try going back to that and it may start. I know you are looking at the engine, but if this suddenly started, it could be the key. If it was running rough and then stopped, you may need something as simple as cap and rotor(4.0).
