I have a 1992 S-10 Blazer 4x4 4.3L vortec, auto. First it started running rough and stalling, now it won't start or starts and runs for a minute then quits. I have confirmed that the fuel pump is good, new fuel filter, plugs/wires/cap&rotor. I am getting 53lbs fuel pressure, all ignition parts working. Problem is, Chevy, in their great wisdom, put the fuel pressure regulator and the EGR valve inside the intake manifold!
My question is-what are the symptoms of a bad fuel pressure regulator and what are the symptoms of a bad EGR valve???
