do fuel pumps slowly ---- out or do they just stop working only?

today my ---- wouldnt start good, then when it did it ran at like 200rpms for a sec like it was barely running, then slowly gets up to normal idle after 15sec or so. but it doesnt fire right up. its like 8 cranks or so not the usually 1-2


its happened a few times in the last day or 2. maybe its not my fuel pump at all?

im running uberdata and dsm 450s. my ***** only at like 5psi right now cause my wastegate is weak or somthin.

its the stock pump on a 96 civic

 

Electrical pump ussually just stop working. Unlike vacume pumps like mine on my b2000 that just died slowly. i could be wrong but this is what ive experienced.

get a walbro 255 for those 450's that should help.

 

electric pumps die slow too.

Check your fuel pressure.

 

ya i know i always let it prime.

im still tryin to get hole of a fuel pressure tester that connects to my car. got one from a friend but it didnt screw on my filter or anywhere
