I have a 99 blazer, auto, 4x4, It has a new tune up ( plugs, cap, rotor, fuel filter, wires), fuel pump, cam and crank sensors, fuel preassure is good, and spark to plugs. I can't get it started. It was running fine, one day had a funny smell, and sputtered a little then died. The only thing I can think of is really bad gas, or a timing issue, anyone have any other thoughts or ideas?

 

See if this thread helps out.
