A few things to address...
(1) Do you have an OBD2 Scanner to connect to the DLC under the Dashboard and Read Codes and System Status of the PCM? If so... Try to use it to record any Codes you can access and post them back here.
(2) Have you been Charging the Battery during the un-plugged time line? The PCM more or less enjoys around 12.5 Volts DC Power to run properly and communicate.
(3) The Dripping Water is likely just condensate coming from the Evaporator if the Drain Tube has gotten clogged with a Moldy Plug inside the Plastic Fascia.
(4) Open up the Under Hood Fuse Box (PDC- Power Distribution Center) and TIGHTEN down the Galvanized Fasteners that Hold the Upper Block to the Fuse Wire Bundles underneath.
(5)
Check around the Engine for any signs of "Rodent Life" as Deer Mice and other vermin like to wear down their teeth gnawing on Wiring, Plastic Coverings and Electrical Connectors. Wear a Mask and Gloves when handling their Feces and Urine soaked nesting materials as they carry the dreaded Hanta Virus and you might get infected if inhaling dust or touching that stuff.
(6) Watch this Video from
@MAY03LT for No Start Diagnostic suggestions to follow next. Take a moment to Screen Print and save the Diagram Drew uses to illustrate how the system works and then refer to this image often while checking off things that make the Engine Start and Run... or fail to do so.
