So, I think my fuel pump is going bad because of the squeal it's making ( ), so I went to check my fuel pressure and here's what I got:

48PSI on prime.
-Slowly decreased to 42PSI if I left it alone.
60PSI on idle/ light throttle pulls.
48PSI on engine shut off.
-Again, slowly decreased to 42PSI if I waited.


Is my pump bad, or is my pump bad AND I HAVE AN INJECTOR LEAK?

On a side note, I'd like to thank GM for putting the Schroeder valve somewhere convenient, unlike my LT1 experiences.

Bump, I know people answer on their own time.. just hope it isn't completely missed.

Yea that sounds like it is done. The pressures seam okay but probably just a matter of time before the pump is done. When you key over without starting the car do you get the same noise for the first couple of seconds?

After driving for a while. If it's been sitting overnight, no.
