Leaking Fule Inj.??

[JASON]

When i cut the car off my fule press. goes from around 40psi to 0in about hour.(dont think this norm.) i have new fule line no leaks. i pinched the return line and it still droped so i gess it is a fule inj. leaking down...if so can this effect performance??(lean out or anything) it has no problems starting. runs ok..just the press. drops fast when cut off......if it is a injecter how do i find out witch one?

my stock injectors don't hold pressure for more than 15 minutes...i think it's definitely time for new injectors for me!

You might find a wet spark plug or one that's a little darker than the others.....but the problem with the pressure bleeding down might not be a problem at all. It could be a stuck check ball or one that was never in the pump to begin with and the fuel is leaking back to the tank through the pump. You can pinch the feed line to see if it bleeds back then. If that's the problem, I wouldn't worry too much about it.
