are you getting any fuel?
a friend of mine had that problem a few years back with his SHO. he put it up for teh winter and it didnt want to start after about a month (he was going to start it every month and let it run for 15 minutes) needless to say we replaced damn near everyy ignition and starting component to no avail... turned out something thru his inertia switch which shut off his fuel pump. i am notsaying this is yoru problem, and it may have been just a fluke with his car, but who knows i thought i had seen it all untill that day...
other than that have you checked your main fuse?
