Problem Starting, Stalling
I recently had my battery disconnected for a few days, and connected for a few more days. There was a power inverter plugged into the jeep's power outlet and now my battery is dead.
i had a friend attempt to give me a jump so i could drive to the store and get a new one but when he went to jump me the jeep just wouldn't turn over. when i started to tap the gas while i was turning the key it fire up but when i left my hand off the key and took my foot off the gas she stalled out and died again. is the dead battery to blame? or is something else also dead.
i was thinking that the dead battery caused my computer to "forget" where to idle?
Re: Problem Starting, Stalling
If the battery is dead the engine will not run. The ECM needs at least 10 volts to stay alive. But if you jumped it did you test yer alternator? 13.6 volts out on that.
Re: Problem Starting, Stalling
i did not test my alternator . not really sure how to test it actually. everything was running just fine a few weeks ago.
Re: Problem Starting, Stalling
so i went out and jumped it again today, had my friends car hooked up to mine for about 10 minutes to make sure my battery got some charge.
i cranked it and stepped on the gas a bit and it turned over and ran fine (in park) but the second i took my foot off the gas it dropped below 1k rpm and died. i did this twice just to make sure it was the same problem and it was both times.
**all of this was done with cables still attached**
Re: Problem Starting, Stalling
Meter on DC 20 volts. + - on battery. Read volts. start it and look at meter should read 13.8v or so if its working. You will need to disconnect jumper cables though.
Sounds like a bad batery
Re: Problem Starting, Stalling
ok thanks, if it dies when i take the cables off i guess i should go grab a new battery before testing the alternator right?
Re: Problem Starting, Stalling
Throw a charger on it for a couple hours. See if the battery takes a charge. If it don't I would guess its the Battery.
Re: Problem Starting, Stalling
i gotta contact a friend about getting ahold of a charger. my broke *** doesnt have one at my apartment here at school
also just went out and started it without the cables attached. but once i took my foot off the gas she stalled/died on me again
Re: Problem Starting, Stalling
I have tested my battery
reading: 12.5 volts
I am about to test my alternator

Re: Problem Starting, Stalling
Sounds like your ECM is trying to reset itself. Try driving it around a few miles.
Re: Problem Starting, Stalling
thanks big jim. drove her around two footing the gas and brake and now she idles just fine thanks a bunch
i think switching from reverse to drive a couple times helped too
Re: Problem Starting, Stalling
Well I am glad to here it was a easy fix for ya. :thumbsup: :driving:
Re: Problem Starting, Stalling
the alternator reading was 14.5 or so when i took the multimeter to it
Re: Problem Starting, Stalling
Big problem driving around town. i still have to sporadically two foot it. itll start fine now and itll stay alive while in park, which is what i meant by idle last night. but, now when i drove to the auto parts store and dropped gf off on campus it stalled once i took my foot off the gas on a straight away and at a few stop signs. any thoughts?
Re: Problem Starting, Stalling
If you have put some miles on it and this persists, the first thing I would do is clean the idle air controller. It meters the air so you have a constant idle in gear or park. Since it will idle in park, but not in gear under a load it sounds like it might be stuck. You can clean it up by using some carb cleaner on it and where it mounts. But don't fill the manifold with liquid. It is located on the throttle body, has a couple of wires plugged into it, unlike the throttle position sensor which has more than two and located on the end of the throttle plate shaft.
