1999 Saab 9-5 starts, after i drive it around and i cut it off it wont start again?

After i drive it around, and i turn it off to start it again and then it doesnt want to start i can hear the starter solenoid clicking, but my car wont start, one time i did that and my engine cut on and then just cut right back off, its not my battery, i took it to advance to check, they said it was good, and ive been having problems with it since my ignition went bad but i got it replaced, and would leaking condensation from the ac, be the culprit? maybe shorted something out? Because all of this started happening when i started getting water in my back floor board, and another thing, I have a bad abs control module, could that possibly be why my car isnt starting anymore?
