Why won't my ford ZX2 car turn over?

So I was trying to install an amp late last night, drilled through my firewall for the power cable, disconnected my negative battery terminal, disconnected the positive, accidentally cause a spark. Hooked up amp cable reconnected positive, then negative. When I get in my car, the radio, the lights, the air everything works fine, except the car won't turn over, it will crank strong but no turn over, I tried jumping it, no good, I took it all apart, removed the amp and power/ground cables, still same issue, I'm assuming the spark didn't short my battery because all the electric is still going strong (I may be wrong) I was thinking maybe a bad starter? But it worked fine before the battery terminals were disconnected and reconnected? Bad fuse? Something to do with the fuel injector? Any advice and where/how to start looking would be much appreciated, thanks.

Added (1). It's a 98 ford escort zx2 sport auto transmission 4 cylinder, it was working fine until I disconnected the battery, after reconnection, it cranks strong but it just won't start. I touched nothing other than the battery, please send help.

"Cranking" and "turning over" are THE SAME THING. Try describing the issue accurately and then perhaps someone can help you. It sure sounds like you need help, because you don't know what the heck you are doing!
