Engine stalls 1994 Dodge Ram 2500, Cummings engine, 156,000 miles, fuel and air filters clean. Engine runs normal until well warmed up after several miles of driving...then begins to run rough...and then quits as if starved for fuel. Engine restarts easily after stalling and can be driven at slower speeds. This problem is sporadic and has occurred in both cool and warm weather. Have been using cetane booster additive in fuel.

    New lift pump installed on 1994 Dodge Cummins. Stalling problem remains.....occurring after vehicle has been driven at highway speeds 10 to 20 miles and after the engine, oil and auto trans fluid are fully warmed up. Engine restarts easily and idles normally after each stalling episode.

    using octane booster will only make the stalling worse, have u run a system trouble code test yest? if not do so, it is the starting point in any problem like this.

    A diesel specialist shop diagnosed the problem as injection pump failure. Estimated cost of repairs: Over $4,000!

  • pttde7 Nov 26, 2012

    Replaced neoprene fuel line segments. Problem solved. South Plains Cummins diesel technician stated that low-sulphur diesel does not cause injection pump failures. The Bosch P7100 injection pump on the 1994 Dodge Cummins models is good for 750,000 miles. No lubrication additives necessary. Replacing the mechanical lift pump with an electric fuel pump may provide more positive fuel pressure at start up..

Sounds like one of a couple things could be causing you problems first would be the fuel pump may be wearing out. these are a mechanical pump and should be producing over 35psi at the injection pump if you have a way to put a gauge on it you could check this under full throttle is when you want to watch it though. fuel gauges are quite inexpensive and are handy to have in the truck anyway. another thing i have seen cause this is the check valve on the discharge of the pump there is a spring and ball in the return line banjo fitting that holds the fuel pressure at a constant 35 psi when that gets weak it allows more fuel to return to the tank which will let it run at lower rpm's but not under full load. hope this helps

    you are either having an issue of pulling air from somewhere or you are losing your injection pump then.

1999 dodge ram 5.2 runs about thirty miles then stalls after running fine just suddenly loses all power sputters backfires engine stumbling badly. crank it up 4 or 5 hours later runs a little then same...


General advice:After warming up track the problem:sparkplugs (even new can have the ceramic parts broken/cracked /wiring (after warming up the isolation get's soft,can loose spark power)/ignition coil(s) (gets hot,stop runnig),running reach,fuel pump/fuel pump relay.Best guess:fuel pump mallfunction (low pressure) related,fuel filter cloged/water in the fuel/fuel line cloged/chipped. Cheers,hope u figure it out,let the people know.

1994 dodge ram stalls out when it warms up


Could be your fuel filter is clogged. If you run your gas tank low often then trash is getting into your fuel filter and that is why it is clogged. Try some fuel injector cleaner that may help.

My 2004 cummings diesel starts & stalls I replaced the fuel filter canister type and truck was fine. Now it shuts off and restarts after sitting a while?


the engine is starved for fuel,are you sure you put on a big enough capacity fuel filter,they come in different capacities,or you could have a pin hole in the line somewhere letting air into the system,or the fuel pump could be getting weak,you can test this with a fuel pressure tester

Fuel pump to prim system don't run very long cummings engine how do i bleed the system after changeing fuel filters


get a 19mm end wrench and crack open the three injector lines you can get to then have someone turning the truck over and it will start pumping air out of the open injector lines start closing the lines up as you see fuel start coming out it will run a little rough for a few seconds until the truck computer resets and then should be just fine.

I am about to change a fuel filter on my 09 ram 2500 Cummings is the procedure the same as the 04 just wait for the electric priming pump to prime the system or no


If you do not refill the filter housing after replacing the fuel filter there is another way to refill the housing.
after the filter is replaced and the cap is secured turn the ignition to run for about 5 seconds then turn to off. again turn to run for about 5 seconds then turn off. Repeat this about 8 to 10 times and then start the engine.
What happens is that every time you turn the ignition to run the fuel pump attempts to pressurize the line then shuts off. That is why you have to repeat the process.
While the truck is running the power to run the fuel pump comes from ecm. Some kind of safety function Dodge has built into the system so fuel will not continue to run if the engine is shut off.

1994 Dodge Ram 2500, Cummings engine, 170,000 miles, fuel and air filters clean. Engine runs normal until warmed up after several miles of driving...then begins to run rough...and then quits as if starved...


Does that 94 have the two fuel pumps on it? If it has the fuel pump on the side of the block and the high-pressure fuel pump on the top, I could almost bet that the one on the block has a check valve going out. Seen I guy spend $700.00 on a new pump and injectors and didn't bother to test the delivery pump. If it does have the primary pump on the block and the check valve goes bad when cold it would run fine and when it gets hot it loses it's prime, it's easy to test just pull the fuel pump off the block and plug the fuel line both sides and while you have it out push down on the actuator with your finger on the suction side and one on the pressure side, if the pump fails to hold vacuum for more than a minute replace it. Otherwise it will destroy the pressure fuel pump and that is expensive. As well the shut off solenoid can be taken apart on some of them and on the back side it has a round disk like on a started solenoid remove the two screws that hold them on clean the round disk with sand paper and the to contact points as well if there is a burr sticking out on one of the contacts file it off with a file then sand it down. Some of the fuel shut off's come apart from the front, either way it's a easy thing to check on both and could save you some big money. Also please rate me as I am a mechanic not a typist so it takes me some time to do this, fact is I could of done what I told ya already if I had the truck. Those Cummins engine was the cats meow when they came out.

Stalls out like its not getting gas


the valve that you are depressing is not an air bleeder it is a shredder valve used to check fuel pressure on, you most likely need a new fuel pump
