Question about 2001 Jeep Grand Cherokee

2 Answers

My 2001 Jeep Grand Cherokee has a hard time starting after I tow my Mini Light travel trailer in hot weather. What is causing it?

I can drive my Jeep from rest area to rest area and when it's hot outside if I go to trun off the engine it doesn't want to start right up. I can let it sit for awhile and then it will start. If I let it run then it's OK. It never over heats. This happened a couple years ago when going through Kansas when it was 103-107 degrees. Also it happened this year in Missouri when it was in the upper 80's.

    I remember this being an issue when I was a kid and the family would take trips in our 59 ford wagon, pulling a fishing boat loaded with camping gear or our box trailer and the same boat on the roof upside down..it was funny to see the car out on the road loaded like that...good mluck..

    Your comment just made me put my thinking cap on. When I was younger I restored a 1946 Ford Pickup and I would be driving along during the summer and all of a sudden I would be on the side of the road. It was a vapor lock in the fuel line or fuel pump. Bring back old memories.

Since this is an older vehicle it is subject to a condition known as vapor lock,,sometimes when traveling in hot climates pulling a trailer, you need to open the hood slightly for all that built up heat to disipate because heat rises..if the hood is kept closed it wont escape letting the engine cool down is a good idea anyway when pulling the trailer..(but only when parked) cheaper fuels will "vapor off " when extremely hot and cause this condition..so if its not an inconvienience youn either take the break and wait it out or dont shut the vehicle off but slightly open the hood and let that heat out..

    I never thought about that at all. When we were in Kansas and it was so hot shutting the engine off was not an option. We would have cooked with the heat bouncing off the black top. All I can say is what you have told me makes a lot of sense. Thanks, Debbie

Solenoid is probably overheating, or positive lead to starter is loose, if so, tighten it. You may want to replace starter.

    Thanks David. The next time I take it in for a service call I will have them check it out. I knew a David Littlefield in high school who was very good with fast cars. You arn't from around the St. Louis area are you?

SOURCE: 1997 Jeep Grand Cherokee cranks but won't start

Same thing happened to me at about 140k. It was the fuel pump. Best way to test if your pump is failing and loosing pressure is to see if the car will start immediately after it has been running, or turn the key to the alt position for a few minutes before starting. If your engine fires faster after it has been running or the key has been in the alt position you will probably need a new fuel pump. Great news is with a very deep socket to get the tank straps off its a 30 minute job to replace the pump/filter assembly.

Check the crank position sensor. I had the same problem in a 1989 cherokee 4.0, and the solution was simply to acomodate the sensor wiring. No replace was necesary

Yes, because it will turn the transmission while you are towing. The problem is that the trans will not be getting any lubrication while it turns. Hope this helps.

My tow vehicle pulls hard to the right while


I don't know what type or brand travel trailer you have but I would have the axle/axles checked to see if they may have shifted on the leaf springs causing the trailer to push to one side or another. Basically have the axle alignment checked on the trailer. Also check the spring shackles and bushings for damage and rot. And check the trailer brakes if equipped for dragging on one side more than the other.

Jeep Grand Cherokee Power Loss


a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.
