Question about 2000 Jeep Cherokee

2 Answers

Engine will only run if gas pedal is pressed all the way

My battery died over night (dome light i think) and when i got it jumped with a jump kit, it will turn over, but the engine will only run if i have the gas pedal to the floor. if i let off at all the engine stalls out. as soon as the jump kit is taken off it is completely dead again (can't even use power locks). I called a garage about getting it looked at and they said over $300 to get it towed and a diagnostic test run :( Could it just be that my battery is so dead? I have had no problems with rpm, fuel, etc until I went to start it yesterday morning and the battery was dead. I also just put gas in it the night before it died..could I have gotten bad gas or water in the line somehow? 4.0L V6 178,000miles

The battery is dead, you know that. (and may be bad)
why, is the only issue.
if lucky just its no good, now, the love to go totally dead after being
totally discharged, like that.
we use charger to see if it has hope, if not a new battery now.
when started was the charge /battery lamp off?
why not take the battery to walfart and exhange it. for new.
take it home and now it starts.
then see if the battery works and holds charge,
charge lamp in cluster out.
or use voltmeter see 13.3. to 15vdc, normal alternator power.
a bad battery (shorted) can cause the altenator to shut down
so, only good battery there is best practices, or go crazy.
right now,im trying to bet my boat trolling battery back to life.
but is hopeless......

if you had a battery charger in your shop
you;'d already know, battery good/bad.

A new battery is a lot less expensive than a big tow bill, for sure. . that is how I would approach the problem

Try replacing the Oxygen Sensors... I had the same problem and replaced my Oxygen Sensors and I haven't had any problems since.

SOURCE: Guages when crazy. Now won't even try to start.

You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)

SOURCE: Won't do anything when trying to start. Jump start and fires up on the spot, but dies when gas pedal not depressed.

Check the ignition coil packs. It sounds like a spark problem.

Something is draining my battery 134,000 M


IT costs nothing to have a load test done on the battery to check for a dead cell which your problems point to. While the engine is running the alternator will be handling the power requirement but the battery will not supply the power required to start.

Car only starts when jumped, quits when brake pedal is pressed


disconnect all the connections to the battery and clean them , also clean all the grounds, check the alternator to engine ground, and engine to body grounds, what you describe is indication of a bad connection and applying the brake is enough to to lower the voltage needed to power the ignition circuit, brake light use a lot of juice

Car starts, when you run it for a while its ok,then you come back later the car is dead, will not start, then you jump it, car starts again


Sounds like your battery has too many dead cells, or your alternator has gone.

After the car has been boosted, turn on the lights, heater, and stereo. If the car wants to die, press the accelerator slightly. If the car stays running, its your battery. If the lights flicker even with pressing the gas pedal, its most likely your alternator.

Where is the Alternator located in a 1997 Lexus LS 400


If the car ran and got you home after a jump start I doubt the alternator is bad. Check your battery. And remember never ever disconnect the battery cable with the engine running.

Starts, but put it in gear, it goes dead. will idle.


1. Had mechanic check timing again. Belt off a couple degrees. Should fix problem.
2. Don't know. this is my son-in-laws car.
3. No.
4. I think valves were bent due to timing belt breaking and son-in-law trying to start car when it went dead.
5. Will do this if timing belt reset don't work.
Thanks for your reply.
