So I was lucky enough to sell my Sebring Convertible to a fellow member on here a couple of weeks ago. So after he came and got the car I decide to get out my 92 dodge ram and clean it up. I was wanting to make a trip to the dump to drop off some unwanted scrap from my bathroom remodel. I put the key in the ignition and she fired right up, ran for a few seconds then died. I repeated this step several times with the same results. Thinking that maybe the battery was low from sitting the last month or so I put my battery charger on it. The next day I go out there and the same thing happens. Starts up, runs for a short while then dies.

Im a bit stumped as it was running when I parked it a month or two ago. Admittedly I dont drive the truck much. Maybe only every couple weeks as I mainly have it for chores and stuff. Today, I went out there and started the truck. It ran for 30-40seconds and I started to think the previous issue may have just been a weird fluke, but then it died again. Then a repeat of before. I decided to put some fresh gas in it. I did not know if this would do anything but figured it would not hurt. Gave the truck a bit of a shake and tried starting her up. Same thing.

So I am stumped. Anyone have any good ideas of where to start? I did check the schrader vavle on the fuel rail and it had plenty of fuel pressure and the battery seems fine. ????

Assuming it won't immediately fire back up, I would see what's missing while cranking. Spark or fuel.

Oddly enough it will fire right back up, but it will only run for a second or two before dying again. Someone suggested a clogged fuel filter or clogged cat converter.

might check fuel pressure after it starts.

Ditto. Check the pressure.

Idle speed motor or dirty throttle body

Pull the battery and have it load tested.Then when you start it keep your foot on the gas for a while or drive it while keeping it running.They do some strange things if the batt is weak or if they have to be jumped.My Durango did the same thing.Drove it for a while after the batt died and it was fine.Rocky

How would I check the fuel pressure after it starts?...on the schrader valve? It's a fairly large schrader valve. Is there s special tool? I hope to take a look at it in the next couple days, but it has been raining like cats and dogs here the last day or so.
