SOURCE: 1999 dodge diesel 3500 transfer pump runs properly

most pumps wont pump until they have been primed,some pumps do something called "cavitate" or another term is "vapor lock"so try cracking the out going line,priming the pump with a little fuel in the incoming line and then placing it into the external container.when you get fuel coming from the outgoing line then you can cinch up the outgoing fittings.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

Check the fuel heater and the intake air heater.
Your injection pump or your injectors may be getting weak
There may also be a leak in the fuel system that is allowing air to enter it.

2004 Dodge ram diesel just die out of the blue.


It sounds like it could be the transfer pump. Turn the key on and then crank the engine for about 1 second but leave the key in the run position and listen for the transfer pump to run. It should run for about 15 seconds after you stop cranking. If not, then you will need to replace the transfer pump with a in-the-tank conversion kit if your is mounted on the side of the engine block below the fuel filter housing. If you already have the in-the-tank pump then it might be siezed or the "sock" might be plugged up with alge or other contaminants. I usually lift the bed rather than removing the tank to replace the fuel module. If the check engine light is on you might want to have it scanned for codes to make sure since the modules can be spendy.

1999 dodge ram 2500 5.9 cummins diesel.won't start.turns over thats it. put in a new intake fuel pump. still won't start.got fuel to the injectors sometimes.


Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

Dodge 3500 diesel lift pump


When the key is turned to the start position, the pump should run for about 20 seconds. Do this 3 or 4 times to prime the pump.

If it still doesn't start, the bad lift pump may have damaged the injection pump. Crack a fuel line loose (don't remove it) and turn the engine over, you should have fuel at the fitting.
