Engine Performance problem
2002 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 98,000 miles
I recently replaced a fuel pump and level sensor due to the engine hesitating, stalling accasionally and sometimes not starting after refueling. Was in the bad habit of running the fuel tank dry which may have damaged the fuel pump (or so I was told) and I surmised may have caused sediment & water in the bottom to be sucked into the fuel line system. The new fuel pump did not resolve the problem as it still sporadically hesitates, has stalled once and has not immediately started after refueling twice. Do you have a suggestion to eliminate problems and would gas additive like Gumout clean the fuel system/injector ports and eliminate the problem? Help !
