Check engine light has reported that the cpu has found sensoes out of parametyers during the checks. Check fault codes for oxygen sensor, idle speed sensor and air flow sensor.

The 4 cyl and 6 cyl engines use a distributor, so no crank and cam sensors.There is a pick-up coil in the bottom of the distributor that could be failing.Code 12 means the battery has been disconnected or the ECM has lost power since the last scan.

Yah sure check the fuel pressure on the manifold, ur belt tension and altenator. But a very common problem with jeeps is the crankshaft positioning sensor. Check and make sure ur gettin fire. If ur not could also b the ignition control module in the distribitor.

HELLO FRIEND . WELL SOUND LIKE YOUR FUEL PUMP GOING OUT . WHEN PUMP IS COLD IT IS WORKING KIND OF FINE , BUT AS SOON AS GETS WARM , THE FUEL PRESSURE IS DROPS . CHANGE PUMP , IF YOU DONT HAVE IN OFF MONEY AT THE MOMENT >> KEEP FUEL LEVEL ABOVE HALF TANK , FUEL WILL KEEP PUMP COOL. GOOD LUCK !!

The code is for coil number 5 on Jeeps that use direct ignition and no distributor. A 1994 Cherokee uses a distributor.In your case it could mean no signal to the coil from the dist.A mechanic would check for voltage at the coil and signal from the module in the distributor.

the fuel pump is in the tank u will need to drop the tank out from under the vehicle and then you can gain access to the pump, you will need to remove the lock ring from the pump module and then you can remove the pump from the tank and replace it with a new one

your timing is out ask a local mechanic to check it out for you ,maybe even the firing order

most of the time it is wires in the drivers door that break in the loom

Ha ha.You ready for this?This is assuming you have the entire lock out
1.Insert the key and turn to lock pos.
2.Using a Torx bit,remove the cyl.retaining screw and bracket.
3.Turn the key clockwise to off.The cyl. will unseat itself about 1/8 inch.DON'T TRY AND REMOVE YET or damage to the halo ring.
4.With the cyl. unseated,turn key couterclockwise to lock pos. and then remove key.
5.Cyl. should come out.
Did you get all that? :)
Hope this helps

start solenoid sounds like the culprit. the start is a breeze to replace. 2-3 bolts and the two power wires. make sure you disconnect the bat. once you have it off the auto parts store should check the starter for free. have them do that befor you buy a new one. also check the fuses if the starter and fuses are good then the ignition is the final link to this puzzle hope this helps
