BlkNight02

I am not real familair with some of the sensors for an 02 chevy camaro all stock but This is a short and sweet situation. Car threw some codes a couple of months ago and light came on and goes off randomly. Not sure exact code numbers but it was the small vaccum leak and MAF/MAP voltage too low possible. Probably needs new gas cap. So, sunday i was checking on some of the two vaccum tubes for the MAP sensor and it was a little tight area. when i pulled my hand back, my sleeve caught the MAP sensor connector and disconnected it while car was running. Car died after about five seconds , plugged it back in and now car will not start. I tried disconnecting the battery for 20 min. , checked ALL fuses, and checked voltage at connector while key on (5v). WHATS WRONG???
