Having trouble with my 2000 Jeep Wrangler. Last week my jeep battery died after returning from town. I had to leave my head lights on for about 5 minutes, but right after I went to start the Jeep and it wouldnt start. Not sure if it was a battery issue or alternator ? I decided to pull the battery from our other car, the Jeep started fine. I took the ground wire off the battery, engine kept running fine. Two days later the other battery still in the Jeep goes dead, if I Jump start the Jeep it starts fine, but died as soon as I took my foot off the gas petal. So I go buy a new alternator. with the new alternator installed I jump start the jeep, it starts right up, BUT again will only stay running as long as I keep my foot on the gas petal. If I take my foot off the gas petal the jeep instantly dies. No sputtering, just dies, like I turned the key off.
If its an alternator shouldnt the new alternator keep the engine running after the engine is started ? or can a completely dead battery still cause engine running issues ?
Anyone have any possible ideas on what might be the problem ? any help would be of great help. As of late if I didnt have bad luck I wouldnt have any luck at all.
