problem maybe fuel, maybe timing maybe valves
 

my truck had a fuel problem when i got it, when i put it to the floor it would spit and sputter. i thought it was just the valvesso i adjusted them, that helped a little, put injectors in it( bosch 370) no difference but more power, put a lift pump in it, big difference. but still runs rough. drove about 30,000 miles and now its back. so i put the old injectors back in and adjusted the valves, that helped alot but still has a slight miss on heavy acceleration. other than that it runs fine. i think its delivery valves but havent got to get thm yet. any info or thoughts helps

sounds like it could be the over flow bolt. have u replaced it yet?

No I haven't, the banjo bolt for the supply line and return line on the top of the fuel filter housing?

no theres a overflow valve in your pump

the return line coming out of the pack of your injection pump has a banjo bolt that restricts fuel, and when they go bad, they will do what your describing :tu:

Overflow valvE didn't seem to change anything, swapped with a buddies that purs like a kitten, but it didn't change anything
