    Default 1986 K30 4x4 BBC Terminator EFI Challenges

    Having challenges getting the EFI setup on my truck. Motor will fire but not stay running. Runs at low RPM (350) about 10 seconds & dies.

    Truck is aluminum head BBC with little bit of cam. Dual tanks, large cap HEI.
    Current situation/fixes: Bypassed the tank selector, currently running only passenger tank, ran all new fuel line from to back, tapped the sending unit on top of tank for 3/8 return line.
    Have correct fuel pressure at regulator, set TPS sensor numerous times. Ran all lines per instructions.
    Fuel pump mounted on frame about 3 feet from sending unit about mid level of tank.
    Pulled plug and see that it's getting plenty of fuel, looking for suggestions/ideas to get fixed.
