Did you check the fuses?

somethings missing here. try to tell the full story, stolen. got it back and what is still broken, phyiscally ??? the key , lock/? or is the key working? (or are you using the bandits, hacks?) or runs ok with the key. but then stalls.? if it stalls ,did the CEL lamp go out too? in the dash CEL lamp at the stall tells you the ECU still has 12vdc electrical power. does it? do the Head lights work at the stall???? and other electrics???????????

Why would you do that?

did you read the FSM first?? http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

What are you torquing the axle nut to? It should be around 170 ft lbs, and it has to have the washer in place. I know several that torqued a lesser amount than the bool called for and it just burns out. Check your torque spec for your Jeep and see how close you are.

Clean the blower resistor connector and retest. Sample pictures here

ask a real question show photos of damage or lots of words to say what is damaged. post symptoms if you see damage say what you see, or post a photo. as you know, damage is limitless, and is inevitable (time and entropy) repost this old post.

change cap get a new one

check the fuel pressure and spark plus and wires

Won't start sometimes is not much to go on, but...does it crank but not run or does it not turn over?If it won't crank (turn the engine) then the problem is in the starting circuit (starter, starter selenoid, battery, battery connections (especially the ground) or starter switch [or the wiring and or circuit protection devices and their connections].If it turns over, but won't run (sometimes) then the problem is most likely either that it isn't getting spark or it isn't getting fuel. There are so many different possibilities here that I am hesitant to begin even listing them. Does it run well once it is started?If it runs well after it is started that would likely rule out some mechanical issues like compression/head-gasket etc.If you post more details about the symptoms, you will probably get more useful information back.

To by-pass the fuse to fix a problem will be a foolish move as the fuses are there to protect the circuit in the event of a dead short. If one wire burns in a harness it normally burns out all the rest so the problem gets out of control. It would be far better to fix the problem in the fuse box first.

You haven't given much detail here but, your condition is likely due to an obstruction to coolant flow. Check the thermostat they are cheap enough to just replace. If that does not help, have the radiator checked for cold spots...used to be you could just run your hand across them but that is difficult...most shops use a heat sensing gun to find them. A good clue to an obstruction is how fast you can fill it without it backing up.
White smoke from tail pipe, water in oil or oil in coolant will tell you that the head gasket is blown. If so, it needs replacement. Of course, check for leaks but most often a leak will give you a delayed overheat and will show itself before that by leaving traces on the ground.Your water pump is fine if its not leaking and the shaft isn't wobbling..
Also check the electric fan to make sure it is running when hot though that too will give a delayed overheat.
good luck, rate answers! any further questions, just ask!

Has anyone checked the fan clutch to see if the fan is pulling enough air thru the radiator when the engine is at idle ?
