If I drive the jeep for any amount of time, shut it down, then try to start it up, it takes about 5 seconds of cranking before it fires up. If the jeep sits overnight it will start right up. Anyone have the same problem or know the solution? It is not that big of a deal but I just don't want to shorten the life of my starter motor. I originally thought it was the fuel pump but I am uncertain.

Re: 1998 Jeep Wrangler hard starting when engine hot
I know that a lot of starters will not start quickly and draw a lot of power if the engine is up to temp. Try a higher CCA battery (Cold Cranking Amp) Battery, your bat may be to low of a rating. If it has a remotely mounted solenoid, not on the starter. If it does it may be mounted somewhere that it gets to hot, relocate to a cooler portion of the engine bay.

Check the crank position sensor. If this goes out, when it gets hot, the sensor will think the crank/timing is in the wrong position. They did this to prevent engine damage in the event that your timing is off. However, when the sensor gets old, as it gets hot, it malfunctions shutting off the engine. Then, when it cools down a bit, all is well. IF IT IS THE CRANK SENSOR, REPLACE IT IMMEDIATELY. Repeatedly trying to start an engine w/the CPS out can throw the timing off. This happened to a friend's Kia Sepphia once and it locked up her engine.
the ignition control modual. its a ox, usaully silver locate on the firewall. it has two plugs coming out of it and will go out or be intermiten for no reson at all. the older fords have them too. there cheep and not hard to replace. i keep an extra one in garage just in case.. good luck and good wheeling
The starter is most likely the problem,tap on the starter lightly with a hammer while trying to start the engine,dont get run over doing this it will take two people,if the engine starts,the starter needs replacing.
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
If you still have freon in it you can try a new low pressure switch. You should find it around the oblong tank. You can unplug the switch and jump the plug to see if the clutch engages. Moderation is the key. Put in the correct ounces of Freon and the system should cycle. Too much freon it will cut out-too little it will cut out. You want the pipes to sweat or frost and the compressor to go off and on. Also be sure you put in an oil charge for that new compressor.
what this means is that either you have a low charge or your expansion valve is failing to operate properly. the expansion valve regulates the ther system which in turn allows the clutch to kick in . 4-5 years is generally the time a system needs a recharge anyway because the refrigerant starts to break down and the system no longer meets the minumum pressures. plus your dryer element most likely needs replacing as well thats where you get the smell from the crystal pellets inside the dryer are no longer any good
