Found it, MAP sensor unpluged.

My first question would be whether or not the pump is actually running. If not are you getting power back to the tank? Could one of the wires be loose or maybe the new pump is bad?

I have a 86 Comanche with a 2.5 that I am putting back together after it had set for a few years. The engine starts but then dies almost immediatly unless you pump the accelerator. It seems to be starving for gas. The fuel pump, filter, and fuel injector are new. The pump has 32 psi and good volume. Thought the problem might have been a stuck regulator so I clamped the return with only a slight improvement. What am I missing?
