Did all of this start before or after you installed the radio ?

After trying to get radio playing.Found out i needed vin number to radio not just reciept.So,i threw radio away and this is what its doing

Do you think maybe the power wire to the radio was connected to a wrong wire to the vehicle? May have blown the ignition fuse or some other fuse that effects the starting.

I checked every fuse.It fires for 5 seconds or so,then dies.Turn key off and do it again with same results

Remove the positive terminal from battery for 10 seconds then reconnect may reset computer.

Taking computer to have it flashed by dealer to see if that clears it up
