well i think my fuel pump is done.... i was driving and at about 4000rpm-4500rpm the car would start lugging like bad like so bad it would snap you forward....like it felt like the motor was not getting any fuel at higher rpms or when you step on the gas but you can still "limp" around so i have a fd fuel pump thats waiting to go into my fc

 

Maybe you just had a really clogged filter.....

 

if you mean fuel filter thats impossible its only two months old had it installed as soon as i bought my car i was thinking maybe shot injectors?

 

How about hooking up a fuel pressure gauge per FSM and testing fuel pump and rail pressure? That is of course a general suggestion, although in your case you do have the pump laying around.

 

I was talking about the in-tank filter, actually. Was that what you replaced? It seems you got another pump without a problem, though, so whatever.

 

Mine was doind something similar when i got mine this weekend i put in a new walboro only to find the same problem turned out to be a 20 dollar fuel filter>> hope this helps

 

yeah the fuel filter by the motor is new and i got a 2 month old walboro for free and its now a new filter on it so hopefully it works i'm going to change it all tommrrow then if that fails well i'll work my way down the problem ladder
