2006 Hummer H3 Q&A
2006 Hummer H3 Question: h3 hummer needs a tune up. What parts do I need and what will the cost be ?
Not sure a tune up or routine maintenance will cause/fix your issue. When it does not start...does the engine crank over? the whizzing sound...do you hears this in engine area or towards back of the car by fuel tank area? - TristanReal
