1993 low fuel pressure KOEO
Howdy! My lt1 is slow to start and has about 10psi key on engine off. 30s and 40s psi idle and accelerating. I just cleaned my fuel pressure regulator before I got this problem and think thats the culprit but want to make sure that's not standard for the fuel pump or filter or something before I drop some dough on parts. Thanks for the help!!

Sounds like a pump problem.
The system should prime to something in the mid thirties when you turn the key forward.
Check voltage at the pump connector when you first key on before you replace the pump.

12.6 or system voltage. Pull insert at fuel filler to access connector. Pressure should be focus.
