took the truck (95 ram 2500 4x4 5.9l) off roading today got very very low on gas and it started backfiring really bad and had loss of power. put gas in it and it still backfires when i get on the throttle but if i ease up to speed then its ok. around 40-55mph it starts backfiring regaurdless tho. any ideas?

 

did you get into the water at all?
if so unplug the coil and dry out the plug. and check and see if you soker the air filter
my dakota does the same thing when i get it in the deeper water.

 

we already tried blowing out the air filter and no it wasnt in water but ill try anyways. i was told fuel pump got damages in a way because i was so low on gas

 

did you recently wash it, or did it rain bad? sounds like water in the dist. or something. doubt the pump went bad, but u can check the pressure if thats what you think.

 

didnt wash it and it was 82 and sunny today.

 

well i am clueless man, never known that to happen with a truck gettin low on gas. im sorry i cant help, someone else will chime in soon enough.

 

Change the plugs. I ran mine out of gas and it did the same thing. Changed the plugs and was back in business.

 

I would change the fuel filter also. You might have had some trash in the bottom of the tank that is now clogging the filter

 

Fuel filter on our trucks is not exactly an easily serviced part.... its inside the gas tank.

 

ok well my gas tank is held on by ratchet staps so i can drop pretty easily but where do i go from there? how do i check psi for fuel pressure and what is the psi supposed to be does anyone know?
