Okay, so now that ive pretty much decided to get a new pump.. I think my old one may be taking a dive.. my car was running very poor at low rpms.. and off idle.. also was running hot. now all of the sudden it wont start.. I do have spark. I can hear the fuel pump coming on.. my in car Autometer fuel pressure guage only goes to 20psi then falls to zero when I just turn the key to prime it. I disconnected the fuel line before the regulater and stuck a cup under it and measure it with a measuring cup.. heres what I found
Prime-(just turned key to start positon)= less than 1/4 of a cup
5 Second Start-(I cranked the motor for 5 seconds)= Almost 1/2 a cup
don't know if this helps.. but is that enough fuel? I confused cause I can hear the pump coming on.. just maybe not enough pressure? or volume? could also of been causing the problems? thanks..
