No radio, no interior light,

check and test starter ---and starting system

Blown fuse

Wires,coils,fuel filter,check fuses,relays,battery connection.

Have the electrical system checked for (a) short(s).

If the starter rapidly clicks when the key is held in the crank position than the battery is low on charge. This may have happened if you had the doors open while installing the radio and the dome light/interior lights where on. Try jumpstarting the vehicle. If it starts drive it for at least 1/2 hour before shutting it off. That should give the alternator enough time to charge the battery for the next time you start it. If you have any questions let me know.
