Question about 2002 Jeep Liberty

1 Answer

Engine turns over but won't start

I drove home from work and parked the liberty. next morning it would not do anything. i discovered a loose battery terminal and cleaned off the gunk and tightened up the terminals. now the engine turns over but it won't start.
i am thinking of replacing the ignition fuses and the starter fuses in the engine compartment fuse box but doubt this will fix the problem.
it looks like an expensive tow charge to the shop and more expense at the shop while they solve the problem.
i will ask for new battery cables because the old one look pretty corroded.
Any other ideas?

    Yeah it starts but won't idle, the engine dies unless I keep feeding it gas.

    I am not sure where the crank sensor is. It looks like some wires lead off the top of the exhaust into the back of the engine on the rear right side as you look on the left while standing in front of the radiator. Anyway, I could not get my hand in there to tap and I wiggled the wires as that was all I could do.

    I took the Liberty to the Dodge dealer and they have to order fuel pump parts and assorted sensors (I already forgot what exactly). I'll have it running soon but it was something I really couldn't have fixed at home. I was able to drive it to the dealer and saved on having it towed. My daughter followed me over and said she could smell a strong odor of raw gas. I could smell it also. Anyway the Liberty has been mostly problem free and it does have almost 100000 miles on it. Thanks

You said it turns over now, so it shouldn't be the battery cables. They had problems with the crank sensor. It is located on the right side of the engine block near the rear. Tap on it and see if it starts. That would tell you if it is bad. But not always. If it don't start, it still could be bad.

    If it starts and won't idle, will it drive ok once you take off? Is it only a problem with the idle? If it is only a idle problem, it won't be the cables. Most likely a vacuum leak or a idle related sensor. Let me konw.

Toyota camry drove home and parked and now won't move? NO ****** ISSUES BEFORE THIS!

It will not move in Reverse either? It could be

- the shift cable has broken
- the parking lock pawl has broken
- park/neutral position switch faulty
- transmission manual valve faulty

I think one of the first 3. There isn't much you can do except have it towed to a transmission shop.

check the connection on your battery terminal ends. if they are loose or corroded that could explain the intermittent no spark. also could be a short somewhere but id check the terminals first. I had that problem once and the car did all sorts of weird things. airbag light, check engine light, randomly wouldnt start until i would mess with the battery.

2004 Ford Taurus, problem started last night. Drove to store, came home & parked. Tried to restart to park closer to curb and would not start. Engine did not turn over. Got low oil pressure message,...

Well your vehicle is indicating a problem, did you or your husband check the oil quantity? If it is low replenish the quantity. Also your battery seems to be failing, when you park it for a long time it will gain a little bit of power, thus when you come outside in the morning it would be better off then if you turned off the car and ran into the gas station to refuel and tried to take off. This shouldn't be a problem if your alternator is working properly and charging the vehicle while you drive. You may want to have your husband remove it and bench test it at a Checkers/Autozone or a local auto parts facility.

If you have more details, or questions email me at

My 1997 Dodge Avenger's engine won't start

Try cam and/or crank sensor. If crank to cam timing isn't detected properly it'll crank all day but won't start. I had similar problem on my 2.5L V6 Avenger....drove home fine, no engine light, next morning it cranked, but wouldn't start. The crank sensor was faulty.
