Open your ditributer cap and check if there is water inside the distributer cap. If there is water present then your ignition spark is traveling to the wrong cylinder. Also, what is your definition of not starting? Is the engine spinning over at all? Is the starter solenoid closing? Do you have power to the starter? There needs to be more info present to direct you in theright direction! Also, check your ground straps, if these late model engines arent grounded properly, you will continue to have electrical issues or problems! One other thing you might check is the seal between your hood and firewall, if it is leaking that could be your water source. Try to find where the water is coming from. It sounds like something could be shorting out somewhere. I really need more info to tell you for certain but here is a starting point. Good luck!
