Please help My S-10 Blazer will start what seems normally then quits as though it has run out of fuel or the ignition system has quit. The fuel pump relay is fine the oil pressure switch for the fuel pump is fine. Fuel pressure is @ 62PSI before starting then drops to 58PSI during the short time that it is running.
THANX a Bunch

 

Check connections at your distributor, coil, or alternator. Check your firing order is correct.
Have your fuel injectors checked, and replace fuel filter.
Check for vacuum leaks at the gasket surfaces of your intake and throttle body. Check all vacuum hoses and all nuts/bolts are tightened correctly.
