Re: 97 blazer starts then stops, new fuel pump, new problem
Is the SES light on? Can you hear the pump run after the engine stalls for a second or two? Have you watched fuel pressure when it stalls to confirm a loss of pressure? It could possibly be that the oil pressure sending unit is not giving the fuel pump current. If there are three wires connected to the OPSU, one of them keeps the fuel pump energized provided there is sufficient oil pressure. OPSU is located at the rear of the engine next to the distributor.

See post #6 in this thread for more details.
