I just bought a 2000 s10 blazer with a 4.3 I replaced the fuel pump, fuel injection spider, fuel filter, distributor, coil, rotor button, distributor cap, plugs wires, battery, alternator, tps sensor, it still won't run I've done all I know to do to it I've been researching online about the passlock II system all my symptoms are basically covered in that. The truck will crank and run fine for about 5 secs and then shut off any idea of what I can do to fix this issue? I already did a passlock system bypass n no luck now the light stays on solid but still the truck won't run any longer then 5 seconds everything is new and replaced
