#452 of 731 Grand Cherokee ('53 2004) Head Gasket Failure?
Oct 27, 2008 (3:05 am)
I would be VERY grateful if anyone could shed some light on my Jeep problem.
Last week, whilst driving my 2004 53-plate (UK reg.) 4.7 Overland model I noticed wisps of blue oily smoke coming from under the engine. Closer inspection revealed quite a majot oil leak dripping through the mechanicals onto the cat and then boiling - hence the smoke. I limped the car home after topping up the oil only to suffer a boiled-dry cooling system.
From experience with a different model I fear this might be a sudden headgasket failure but really I have no idea. I cannot drive the car (parked outside my flat here in London). Need to have it flatbed-towed to a garage but before I do, can anyone give me some idea of what might be wrong?
I have not off-roaded the car for about 6 months and there have been no other problems whatsoever. It has done 60000 miles now.

#454 of 731 1994 Grand Cherokee dying while driving

Hi. just recently, my Grand Cherokee has decided it wants to just die while driving down the road. The electronics still work fine through this. The engine just shuts off. If I am moving at the speed limit, iI can usually pump the accelorator a few times, and the engine will start on its own. However, I have been at a stop light, and the thing just dies. I then have to put it in neutral, and turn the ignition. It will not fire up right away, but after a few tries, it will go again. Help would be greatly appreciated, and make impatient drivers behind me happy!

happened to me in my 2001 and I replaced the crank sensor and now works perfect.

This engine runs great except as follows: After reaching normal operating temp, the engine is turned off and the car sits for 20 or 30 minutes. After re-start, the engine misses and backfires during normal acceleration to 30 MPH. I have to feather the gas or rev the motor to clear the problem. After this first acceleration, the engine runs fine. The milage is 110,000 and this problem has been going on as long as I've owned the vehicle (15,000 miles). I recently replaced the plugs, wires, rotor, dist cap, coil and crankshaft position sensor. Any ideas would be great.

Well, here's what I think. It's your fuel pump. Just replace it. My reason is that I had one fail on an older car (not a Jeep) and the symptoms were about the same. The car would almost die when climbing hills and then perk up going downhill. I hope this helps. Let me know if this works.

I just experienced similar problems with my '93, so I changed electronics plus the fuel filter, with no luck. I bought a fuel pressure kit (hoses/gauges $15 auto stores) and found my fuel pressure was off by 50% (data in repair manual $20).
After testing the fuel regulator (OK), I decided to change the fuel pump. This was no easy job, as my fuel pump is located INSIDE the fuel tank. Don't attempt this without assistance.
You'll also need a floor jack, 3 ton car stands, upper body strength and lots of caution working around a gas tank! Call local auto stores, salvage or websearch for exact fuel pump match, so you'll need it in your hands. Of course, this means you'll have to take it off the road for these repairs. I used a self-service salvage yard, LKQ, and saved over $250 on the pump.
The fuel pump has a LARGE plastic securing nut holding it to the tank. Use a wide blade screwdriver and hammer to gently tap it off. Be sure to replace the rubber seal with a new one (Jeep $15).
I hope there is a solution for you somewhere above.

2004 JGC Laredo 4.0L, 2WD, LHD, MTC, A/C and heating wouldn't turn on; turn signals wouldnt turn on either. Flashers do work, dealership stated that it was an inoperative heater blower motor, blower motor resistor module, and a inop multi-function switch. Replaced all. 10 minutes later, driving away the heater quit (nothing at all, not even cool air) and the turn signals quit also. Still not fixed. Today, the vehicle overheated while running in the opened garage (it is about 30 degree's here). This vehicle has not been run much lately, has NEVER overheated. All I can think of is a power surge or short on the A/C and the turn signals (a fuse was blown, no it's not the fuse). Maybe something electronic on the overheating (its not the thermostat or the pump....). Prior to this, NO ISSUES. Vehicle has about 58,000 miles, is garage kept, and maintained well. I think its an electronic bug somewhere. I know the first two issues are connected and now I think the third has joined the others. I've heard of a lot of issues with the Jeep but this is the first on my three problems (heater wont turn on, A?C; turn signals same, overheating...). midnightrider64hotmail.com

My 88 Cherokee 4.0 inline six cylinder, 5 speed manual, loses power when going up a hill whether the hill is a steep one or not. It's much worse at losing power on steep hills...it even loses power when downshifting to get more power.
What could this be?
#461 of 731 1993 Grand Cherokee will not start
Jan 02, 2009 (3:29 pm)
Hey, hope someone can help with this, 1993 Grand Cherokee 318, didn't start from one minute to the next, replaced the fuel filter, we have a good spark, all electrical works, reading the forums it seems to be the crankshaft position sensor which I bought. I found the electrical connector for the sensor by the dist cap, followed the wire to what feels to be the sensor, there is very little room to maneuvre your hand let alone tools, am I missing something ? It seems to be behind the engine block on the passenger side next to the distributor, can't visually see it just feel for it. I removed the passenger side Valve Cover, which is giving me a bit more room, but still can't see it. Am I on the right track ?
