Fuel pressure regulator or fuel pump?
Fuel pressure regulator or fuel pump? Hey guys i know i've been having a fuel problem for a while finally getting around to working on it went and rented a pressure gauge from autozone and put it on, heres the results...
prim key get no pressure, prime key again get like 10-15 instant drop after, if i keep going it keeps building pressure up to about 30ish psi then instantly drops... Go for a start crank crank crank starts psi is around 38ish... pretty low compared to the 43.5 psi its suppose to be, unplug the vaccuum line on the fpr and still around same psi no change... went for a drive and it drives at about 35-38ish psi until i step on it psi drops to about 30 and then my low rpm misfires start to occur.... fuel pump was installed in april its had these problems but i've been really busy moving across country to worry about it until now....

also i forgot to mention that my regulator line does smell like fuel, the car runs extremley rich at idle, enough to were your standing there and your eyes burn... and when i unplugged the line today after it was running the fpr hissed at me, vehicle not running so it wasn't the line onnected to the intake haha

im just going to replace both, the pump thats in there im not confident about it was a need something right now kind of thing, probably just going to order pump and regulator because i do smell fuel in the line, and see how it runs, it got a lot worse today throttle conditions netted me as low as 15 psi... dohhh!
