I have a 2005 GMC SIERRA 2500 HD, 6.6 L . I have no power when pedal is depressed. It will idle in the driveway all day long until you give it the fuel and it boggs out and puts out the billow of blue smoke. It will idle along the road but when you give it the fuel it looses power. I changed the fuel filter and no change. There is no leak around the fuel filter. The two wires in the WIF sensor were corroded of. Would that make a difference?
