battery shows full charge on batt. charger (left it on over night). when i turn the key over lights on dash (radio) go out and nothing, all i hear is the fuel pump humming. what could it be, trans shift sensor maybe? trans was shifting rough past couple of days. any other possibilities?

 

I would start by taking your battery to a parts store and have them check it. It may have a bad cell in it. Also check all your grounds and ignition fuses

 

Try starting it in neutral.

 

I just had the same problem. I cleaned my Neutral Saftey Swiatch this morning, and it fired right up. I second the try starting it in neutral. I cleaned all my connections to the battery, and checked all the relays also.
