I have a problem with my truck, I need your advice. Can you help me?
I have a 2003 gmc Sierra 4.8L Ext. Cab 4x4
high mileage. It runs great when you
started up and drive it. Once you turn it off
for a while. It starts up fine, but when you
try and drive it, it skips an it has very little
power. When diagnose it say the fuel
injectors are only working on one side. My
mechanic said the fuel pressure is fine.
He's changed out the computer, tune up,
catalytic converter, check the fuel
injectors, check the wiring harness to the
engine and working on checking the wiring
harness from the fuel tank to the
computer / engine not sure which one. I
am not a mechanic. My trucks been out of
service for three months now. Can
someone make a recommendation?
