OK today i went to best buy to go get a radio installed. After they installed the radio they started the car and backed it out of the bay. So i go get my keys and go out to start the car and the motor now wont turn over . Any ideas of what may be wrong? i know its not the battery and it seems to be getting spark i think, but it feels like its not getting fuel.

any help would be appricated thanx
