GreenF350 Posted May 25, 2011 Share Posted May 25, 2011 So before I go diagnose this, I figured Id throw it up here. Gotta love jeeps. Anyways, my jeep will fire right up, and within 3 seconds, shut right off. This came out of the blue the other night, and I havent had time to look at it yet. I wanted to go wheelin this weekend, so maybe u guys can help me out. Like I said, fires right up, then dies right after......Throw out suggestions, I'm going outside to figure this out.

flint54 Posted May 26, 2011 Share Posted May 26, 2011 Fuel starvation? Unable to maintain pressure at the rail due to filter or pump going south? Link to comment Share on other sites More sharing options...
SW86 Posted May 26, 2011 Share Posted May 26, 2011 mine will do that once and awhile but right after it dies, when i fire it back up it high idles for a few seconds then drops to normal. sometimes ill have to tap the gas to get it to drop. :dunno: didnt mean to :hijack: Link to comment Share on other sites More sharing options...
Fezzik Posted May 26, 2011 Share Posted May 26, 2011 what year/engine do you have, the ballast resistor on the drivers side fender is a popular culprit, it is a white block with 2 wires attached to it, the quick check is to jump the two wires and see if it stays running Link to comment Share on other sites More sharing options...
jpdriver1 Posted May 26, 2011 Share Posted May 26, 2011 be sure to check the fuel pressure at the rail -- just went thru this myself -- would start, run, but die when a load (driving) placed on the engine -- found the hose from the fuel pump to the metal line was nearly closed off -- replaced the hose -- blew the doors off a hot shot in a "race" ricer and gave a camero a run for his money :banana: Link to comment Share on other sites More sharing options...
Geonovast Posted May 26, 2011 Share Posted May 26, 2011 2nd on the Ballast Resistor. Jump the two wires going to it, and fire it up. If it stays running, you've found your problem. Link to comment Share on other sites More sharing options...
