92 wrangler stalling problem

I have just took ownership of this jeep, first one ever I have noticed today that after starting, it stalled and then would not start again. I would turn the key on and i could hear the fuel pump working. I waited about ten minutes before trying again. It started up and was idling fine then it would start to sputter and wouldn't idle right. I would accelerate the throttle and it would seem fine just wouldn't idle. Any ideas??? Again brand new jeep owner so sorry if this is answered somewhere else

I just bought my 93 YJ in November and it was also my first, so I'm not an expert by any means or even very experienced. My YJ's a little B***h to start in the mornings but I start it to get it warmed up to go and it idles just fine. For you it might be the fuel lines or maybe even the battery possibly not sending enough power to the pump when you idle. I would sit down and turn the key until the red check engine light pops on and sit there and listen to the pump, if it starts to get quieter then it could be the battery like I said. Again don't take my word for anything I'm just speculating on possibilities because I've gotten so much help from here I thought I'd try to give a little help back for once. Good luck and I wish you all the best sir!

You could take the battery Out of the jeep after you start it, and the alternator would keep it running.

there is no check engine light on, the jeep hasn't been sitting all that long. the voltage seems fine as well. i was thinking about replacing the sending unit with the fuel pump not sure if that might help.

Welcome to the forum. I am on the PC finally.

Check your codes like Goob said and post back what you get:

It appears that it's a 12 and a 33 I started it up to move it and it ran for a few minutes than it stalled, I re started it and it felt almost like it wasn't getting fuel. Now it cranks but won't start.

Check for spark at the plugs and fuel at the fuel rail.

Ok just an update, went back out and tried it again still cranks but no go. I did replace the fuel filter over the weekend as well. I opened the hood and moved the wires that go to the distributor and nothing else and went in and tried It and it started up again. Don't know if this is the problem or just a fluke thing. Could it be the fuel pump not pumping enough. I have been thinking about changing the sending unit since the fuel gauge doesn't work right anyway.

Dont throw parts at it. You need to see what part of the system you are losing fuel or spark. The next time it doesnt start push the valve on the fuel rail and see if you get fuel to shoot out. Remove a plug wire and put a phillips screwdriver up inside the boot and the otherside near ground on the block. See if it arcs. There are way too many things that can be going on. You can spend a lot of wasted time and money trying to figure it out.
