Umm... So what exactly is it doing? Is it turning over but not starting? Is it turning over and chugging but stalling out? Is it clicking but not turning over? Are you getting spark? Are you getting fuel pressure at the rail?

What motor do you have? V6 or 4...if its a 4 you may have gotten water down around the spark plugs and boots although usually its water in the coil pack...try letting the car sit for a few hours or if you have a leaf blower use it on the motor to dry it and then try starting it again...usually water on an electrical wire that is exposed will cause this. Never Power Wash your motor....ever, the high pressure water can hurt the wiring and in result cause this to happen. Use a water hose with just running water and keep an eye on what your spraying it on.
