2002 Trailblazer - trouble starting engine

[gch]

For the last six months, I've had intermittant problems starting my '02 Trailblazer. When I try to start the engine, it turns but it does not start. After attempting another 2-3 times, it still does not start. I wait 8-10 minutes and attempt again and finally it works. When it starts again, the car emits an odor not unlike rotten eggs. I've had OnStar perform diagnostics on the car, and they have been unable to find any problems. I have taken the car to three different dealers. They replaced some sensors, but this obviously did not fix the problem.

Have any of you had any similar experiences, and if so, what did you do to solve it?

Thanks.

check your fuel line... (pump, injectors..etc)...it could be a lot of things. is there anyway that you could describe the problem even more??? how has it been acting lately?

ps: onstar only works if you have a Service Engine Soon Light or Serivce AWD Light.
