    87 Chev issue

    Sometimes itll start with a little bit of throttle and be fine (after throttle is released). Sometimes it'll die a short time after the throttle is realeased. Sometimes it'll stay running if I keep a little bit of throttle...sometimes it doesn't. In attempting to start checking off the basics, I'm installing a fuel press gauge (setup from RV Morse) to make sure fuel press isn't dropping off for some reason. My question at the moment...I've disconnected both fuel lines at the throttle body and turned the key to prime the fuel lines and am getting fuel flowing out both the pressure and the return lines. This doesn't seem normal to me. What do you guys think?

    If you guys have any advice on what to check after I've checked fuel and spark let me know.

    A little bit about the truck:
    mild build 383
    670cfm holly throttle body
    bored endlebrock intake
    Full msd system
    stans Tri-y headers
    EGR delete
    tuned by old school efi
