Chevrolet Corsica Gas Problem
3.1 V6 MPI
Car tries to start...cranks, fires about 2 seconds, then dies. I have installed a new pump w/strainer in tank, new MAP sensor, new IAC valve, new oil pressure switch, new oil filter, new oil, new fuel filter and fresh gasoline. Gas cap vents fine. Fuel Pressure at Schrader valve on rail shows 42 psi (pump on). Pressure will drop (pump off) to 20 psi after minutes. No noticable fuel in vacuum connection at pressure regulator.

if you remove the hose from the regulator, does fuel shoot out??
