I own a 1992 Chevy S-10 Blazer 4x4 with 4.3L Vortec, auto trans. My once faithful truck first started running rough, then stall, wouldn't start for an hour. Changed fuel filter-it drove 15 miles fine, then run rough, then stall.Hour later it starts, runs about 4 miles to home and dies. I put on many parts recently including dist cap/rotor, plugs/wires, fuel filter, air filter, checked all vac hoses and computer codes. I am getting full voltage to starter, full power to all plugs, and just did a fuel pressure test which checked out 100%- so I know my fuel pump is working, my ignition is working too. The fuel pressure regulator is underneath the intake manifold and have no way of testing it.Could this cause it to not run? Also, a manual said that if the low oil pressure switch is defective it won't start-is this true?Why isn't the computer giving up an error code?The computer checks out also-WHAT COULD IT BE!??
