Question type: Maintenance & Repair

I have an 2007 Chevy Trailblazer that i put spark plugs in last night. Its been
driving fine until i left for work this morning. I was headed in to work and i
started smelling gas. I know this may just be coincidence of something that was
already in the works, but i am hoping to get some ideas on where to start
looking. Please Help.

Take a peak at the fuel regulator. On drivers side of the black plastic resonator above the spark plugs. Located under the resonator, nearest to the front. That can leak and cause this smell, can be a tough one to track down, but I've found this to be the culprit.
