94 Jetta will crank but won't start

I would pull the radio and check all the wiring.

I already did its hooked up correctly. The engine cranks but doesn't fire/

Try some starting fluid. If it fires, it's a fuel delivery problem.

Its not getting any spark from the coil, haven't gotten around to checking if its getting fuel but I believe it has something to do with the antitheft system, manual says it won't let the car start if you don't put the code in the radio after its taken out and put back in I know the code but the radio doesn't work and I know I got it plugged in correctly I think there's some sort of radio fuse that is messed up. any ideas?

check ground wires everywhere he was, a bad connection could cause this.
