usually when i turn the car on to accessories i hear the fuel pump turn on (holley 255 lph) but now its not for some reason, in fact i dont even hear it when im driving. the car seems to run ok though it idles around - 450 bar and gets boost a little slower than it should. i cant figure out whats wrong though.

for reference my setup is:

t3/t4
255 fuel pump
dsm 450's
custom piping and intercooler
vafc hack
tial 35 mm
custom manifold and downpipe

check the ground,and the wire tap into the distributor

 

FYI

Mine just went out. I droped in an in-tank and kept the inline in place. If the holley is an inline (mine was, so i am assuming here) then make sure you remove it. There is a check valve in there and it will stop the flow of the gas from the good intank pump. My car would hit a wall at more that %20 throttle and 3psi....

 

well im just concerned cuz i dont hear it but it seems to be working cuz the cars not leaning out and runs okay ( i think i have a vacuum leak)

 

ttt, help me, im lost

 

You installed an intank fuel pump right? Not an inline correct?
