Seems like you've done all I would have suggested. Since it only overheats when in idle, I would think that it would be a flow/circulation problem. What kind of belts do you have on a '94 5.2? My '98 5.2 only has the serpentine belt. If the fan is belt driven it may be loose enough to where you...

A bad crank position sensor will sometimes cause a no start. With the switch on, notice if the check engine light comes on and goes out with all the others. If it doesn't show, then you probably won't hear the fuel pump prime(the whirring sound you get when you turn on the ignition switch). The...

Glad you guys are here to help. this is a great site and I'm glad to be a part of it. Thanx again:shades:.

Sounds like good advice.....May be the Cat. I seem to have noticed that if I ride over a chuck hole (bump), I got the same rattle. You're right it does sound like a bunch of loose bolts. Haven't hit the cat with my hand yet; just got home and waiting for it to cool down. Could this be why I...

Have noticed a rattle that seems to be coming through the exaust. when i give it a little gas it goes away. not there all the time. could it be a loose timing chain?

Remembering a time when I would be driving along and suddenly it would slow down and speed up(jerking). Giving it more pedal wouldn't seem to make much change. Ended up installing fuel pump.

Thanks....After all it is a man made product. Will try it today. Any way you help me on testing a relay? There are several prongs.....

Am grateful the advice, but am not familiar with BCM and ASD. Could you please elaborate? Thankx

when you say jerking , does it seem to lose power and then suddenly take off?Do you notice almost no pedal at all when you give it gas?

What's a DMM? Scan tool keeps giving a 'link error'. Am I correct in assuming that a Bus communication error would mean a bad fuse? Tell me about the DLC.:???:

Sorry for the confusion. I was trying to be brief... Let's start over. The jeep was running. I had just drove the kids home from school. I went back out to the jeep after a short time(maybe ten or fifthteen minutes) only to find that it would not start. I noticed that the check engine light...

Have replaced Crank Position sensor and Magnetic Pick Up Sensor (located under distributor cap). Have checked all relays/fuses under hood. Fuel pump will not prime(installed six months ago). Parked Jeep and came back out to start ten minutes later - would not start. Overhead display only shows...

Is there a way to determine if the Power Control Module is any good or not? Am using a hand held diagnostic and keep getting 'link error'. Checking for codes on a '98 Grand Cherokee with 5.2 engine.

Thanks for the quick reply. Checking wiring harness for breaks in line but did not find any braeks. Only three wires from harness to pickup connecetion. Any chance the wire could be broke within the insulation? Wires not hard or cracked; as said before, wiggling them seemed to solve things. Not...

If it is indeed a sticky lifter it may account for why it shows up more on cold starts. There are many solvents to add to you oil that may/may not help.The Murphy brand is pretty good as well as Gumout and Risolene. I once saw a guy pour a small amount of transmission fluid into his carb while...

Having trouble with wiring connection in my magnetic pick up coil. Also called a camshaft position sensor. Located under the distributor cap below the rotor. Have a 1998 Grand Cherokee Limited with a 5.2 engine. Problem is when driving, it would shut off and if I got under the hood and jiggled...

I don't consider it as going down the wrong path. Look, you thought you could help and you were good enough to pass on a few pointers from what you have encountered. lots of people dodn't even go that far... besides, I followed your lead and checked for bad grounds and breaks in the wires. Then...

MudderChuck - Did as you advised and checked to see if in fact the check engine light came on when I turn on ignition..... all lamps in the dash cluster come on and after about 3 seconds they all go out.The check engine lamp didn't show up at all. The low fuel lamp came on with the other lamps...

Thanks, for the response, Tony. I checked the battery connections and they are dry and tight. Still trying to trace the wiring for a possible break as MudderChuck suggested. No luck so far.....
