i was driving and came to a stop felt my truck struggling to idle so i put it in neutral and it ran better but not normal. i started rolling and then it was sputting and doing everything a bad fuel filter would cause. but what i dont understand is i had a friend rev it when i was at the tail pipe and white smoke + sparks came out. im seriously concerned any help will appreciated..

 

Low on fuel, bad lift pump, clogged filter???? I dunno, out of ideas. The sparks is not a good sign at all, IMHO.

 

Somthing bad in your turbo pull the intake boot off and check for play in the compressor wheel.

 

truck has 3/4 tank turbo has no play but the fuel filter today was colgged and rusty. what could this mean?

 

Hows it running with the new filter?

 

X2?

 

Rusty fuel filter means a rusty fuel tank, or rusty lines corroded by water that can cause a spark in you ingnition but its also proably running hell on your injectors on injection pump.

 

the truck runs great now. i have all stainless steel fuel lines, composite tank so its not possible for rust and i think its only rusty since when i did the head gasket i left the intake hor off and the mount for the fuel filter and havent really remebered to do the fuel filter. im doing a full cleanout of the fuel system and will let you guys know how it goes.

 

sounds good!
