#1697 of 5134 1994 Jeep Grand Cherokee Ignition Woes ! Help !!
Jul 29, 2005 (4:33 pm)
I have a 1994 Jeep Grand Cherokee 5.2 V8. Once you crank the engine, you have approx. 15 minutes of drive time or idle time before the engine shuts off. Then, after waiting for about 15 minutes off not touching anything, it starts back up and drives fine for 15 more minutes. I originally thought it was a fuel pump problem and replaced the pump. But the problem persisted. This time, during one of the "shut down" episodes, I checked for fire to the plug wires and "no fire". I also used starting fluid in the throttle body to make sure, it was not a fuel problem. There is not any warning signs when it shuts off. It just shuts off the motor as if using the key. When it starts back, it runs perfect. Any ideas what the problem could be. I have checked all the fluids to make sure a sensor was not shutting the engine of.

Just a shot in the dark, but I've heard of people having problems with the built in security system. I don't really know anything about it or what the symptoms are or even how to check it...but give it a search on this site see what it turns up. Also search google. Good luck.

Yep, it's "aged" enough that it could easily be the compressor.

That could be a ton of things.
I have a '98 and had to have the rear axle/wheel bearings replaced at around 100,000 miles.
It basically was making a constant loud "hum" (for lack of a better term) that increased with increasing speed.
It was more noticeable when the rear seats were folded down.
Cost almost $900 at the dealer but has not reoccurred.
That was really the only problem I had with my Jeep that I felt shouldn't have happened.

thanks for your post. It is good to hear of someone with a problem free car. I am hoping to have a trouble free ownership.
Warranties, are tricky as they are $2800 for 3 yrs/36k. I want to take my chances, but some of these post make it sound very risky!
Is yours a FT/4WD?

99 jeep grand cherokee. I have changed diff. fluid but still have a howl when driving

We have a 2001 Jeep Grand Cherokee with 83,000 miles on it. Recently, we replaced the battery and the air filter. About 750 miles after we changed the air filter, the malfunction indicator light appeared. The handbook says it may be fuel or emissions related. My husband took it to the dealer and they said it has to be tested first ($75.00 minimum to diagnose) but the problem would probably cost around $200.00 to repair. Anyone else encountered this problem?

I've recently had the water pump, thermostat and belt replaced in my 2000 Grand Cherokee Laredo. The ac unit was working just fine but now it blows whatever kind of air that's on the outside, which lately, has been very hot. There is freon in the unit. Can/will anyone help me?
Also, on a different note, when I open the driver door, it gives a pop sound. I've sprayed WD-40, still does the same thing, other than these two things. I love my Jeep!

My Jeep will have a different 4WD setup than your LTD. I have a 4.0L Laredo with the SelecTrac which is not full time 4WD.
It is selectable but I do use the 4WD a fair amount. I have not had any 4WD related issues.
Whether a warranty is worth it or not is always a gamble. I haven't even come close to putting $2800 into my Jeep in the 7 years I've owned it. It now has over 167,000 and is running strong.

If the vehicle is still running fine, I would drive it for a couple of weeks to see if the light goes out.
A loose gas cap can turn on the light. If that's what it is, the light will go out after several drive cycles.
The dealer sounds a little questionable. How can they possibly know how much it will cost to fix it before even diagnosing the problem?
