So I'll be driving her around and after about 5 min the engine will just die out of nowhere! Everything else stays on (radio, headlights, dash) but the engine just dies and I have to pull over, wait a couple min and shell start up as if nothing happened it'll drive for maybe 2 min after that and die again.... Here's what I've changed so far: ignition coil, ballast resistor, spark plugs, and wires.... I've spoken to some guy I met who liked my duster and he said it could be the fuel pump. I would believe this especially because it'll die after accelerating... I just wanted to get a second opinion or even some more ideas of what it could be. Thanks |

I had the filter on the fuel pickup in the tank collapse and starve the engine. How clean is your tank and do you have fuel pressure when the car dies? |

Well I had the fuel filter changed too I forgot to mention,and the fuel tank was one of the first things that was cleaned... I don't know if it has pressure but when she's dying if I repeadeatly press the gas it'll sputter a lil but then it'll just give out and I gotta pull over |

Defiantly a fuel delivery problem, supply is not keeping up with demand. It could be the pump, but most likely there is crud between tank pick-up & pump. When you cleaned the tank, did you also blow out the fuel line? Dose your oil smell of gas, and or, showing high level on dip stick? If so, suspect a ruptured fuel pump diaphragm. If this is the case, don’t run the car until you change the oil, and replace the pump. Thinned out oil will quickly wear engine Barings, and also there is a possibility of igniting those fumes in the crankcase. |

Yea we did blow out the line, we can smell the fumes of gas but not from the oil, it's more noticable near the fuel pump, but I will change the pump and oil as suggested just to make sure... Thanks! |

Before you pull the pump, disconnect the tank side line, and have a friend crank over the engine a bit with you finger tightly placed over the inlet that the tank line was connected to. If it is working properly it should stay sucking your finger after the engine stops turning over. If suction doesn’t last, the pump’s diaphragm is ruptured, time for a new pump. Before you change the oil, pull dip stick an give it a good sniff for gasoline. If it smells like your gas tank, the pump has been leaking into your oil pan. Where you smell gas over on the pump side of the engine, another possibility could be in play: that being, connection of fuel lines to pump are not tight; or the fuel line to tank has "pin holes" in it. If the vacuum side is pulling air, gasoline will not be delivered in sufficient quantity to the carburetor to run the engine above an idle. Do the cheep stuff first, than if needed, start spending money. We don't want you to just start replacing parts without performing diagnostic work first. With careful observation, and systematic checking, you should be able to narrow the problem down to one item. Bill |

When a Mopar dies instantly w/o any preliminary symptoms, I've found that it's usually an ignition problem. Generally, fuel problems seem to take a little longer to get bad enough to stop the engine. |
