Firebird65

1997 s10 with the 4.3 engine, recently I had done a tune up to the vehicle, went to crank it afterwards and it tried to crank, then stopped. Now I have no dummy lights on the dash with the key in the run position. The only lights that come one are the airbag and seat belt lights. Also the fuel pump doesn't prime in the run position like it should. Since this issue I have checked all grounds, fuses, and even replaced the ignition switch. The vehicle is currently in a no crank no start position. Any help would be appreciated. Thanks in advance.
