    Put a new filter in tonight and checked the pressure. While the pump kicks on right after the key its at 52psi. Then it drops to about 42 and stays there for the most part. Bounces from 42 to 46. If I push the idle up over 2k it drops down to 42 and stays there.

    What I have read on the L36 is that the pressure should be up around 48-55, but it doesn't state if that is running or with the initial pump start?

    If I take the vac off the regulator it jumps up to 50psi and stays there.

    Check OHMs on the injectors are most were around 13.1.

    How do you know when the regulator is shot on these?

    Thanks in advance for the help.

    Yes, I did a search and saw all sorts of accepted PSI pressures, but nothing where the book says they should be running.

    Pressures seam good. Hook a vac pump up to the regulator vacuum line and see if gas comes out.
