12'SROCK Posted May 13, 2008 Report Share Posted May 13, 2008 also a cause of injector/pump failure is running your tank on low fuel. . . . .not good. . .pump gets hot, pump picks up debris at the bottom of the tank Quote Link to comment Share on other sites More sharing options...
wody Posted May 13, 2008 Report Share Posted May 13, 2008 (edited) I don't think it's wheel bearings if it is both passenger side wheels....sounds more like the wheels need to be rebalanced........... start with the easy stuff first. also a cause of injector/pump failure is running your tank on low fuel. . . . .not good. . .pump gets hot, pump picks up debris at the bottom of the tank sounds logical to me. what is your MPG?

riddle Posted May 13, 2008 Report Share Posted May 13, 2008 prolly bad fuel, change out your fuel filter often, change gas stations, dont run your truck on "E". Use A High quality fuel system cleaner, BG products, ie 44k. or gm top engine clean. If You get the Injectors profesionally cleaned as soon as it starts running rough, that may help. ~Danny Quote Link to comment Share on other sites More sharing options...
