I have a 02 Chevy Silverado 1500 with a 4.3 and its
getting no power, already changed all the wires
plugs and rotor button and cap plus the mass air
sensor what else could it be?
that makes me think that the fuel injector might be bad and it could also be your timing belt. listen for a rattling that is the timing belt goign out. but i would try flushing your fuel injector first
Well replaced the fuel injectors and still doesn't have any power and it doesn't seem out of time
