quick fuel question

[smithers584]

ok so i have my FPR set at 38 psi on a s13 sr20det. i just drove it to grab a bite to eat, came home and ate, then went to work on the car and noticed in the meantime my fuel pressure has already dropped to 0. is this normal, i have never seen it before on my car, sounds kinda odd.

thanks

well fellow josh, mine does this after about an hour from close to 45psi on ka,I think someone said leaky injector or seals

[Ritz S14]

That is normal.

ok i know that overtime it is supposed to release pressure, but this just seamed to be real fast. anyway, i know it is definately not a leaky injector, i pulled the full rail back and primed the system and there isnt the slightest bit of evidence showing that an injector might be leaking. thanks for the help guys.

Nope its normal. I have new injectors and injector seals, my pressure drops right when I turn off the car or like a min later.

when i turn my key on the fuel pump turns on, my pressure goes to 43 then the pump turns off and it goes right to 0, that shouldnt happen right? the pump is a walbro 255
