After sitting in my driveway for a week through some heavy rainstorms i had trouble starting the car.  It would run for a couple of seconds and then stall.  After a few tries it started but while I was driving the Theft System light came on and stayed on all the way to work.  After work I had the same trouble but the car eventually started, the theft system light did not come on.  Made it home and now it won't start.  Same as before runs for a few seconds.
Here are some things I noticed.
1. The interior lights do not come on.
2. The radio does not come on(clock does not either)
3. The electric door locks do not work
4. when the key is on the position the Theft System light stays on steady
I tried the Passkey Fix but it did not work the light never goes off
5. I can hear some random ticking from the engine while I was waiting for the Theft light to go out.
6. I hear the fuel pump when I turn the key to the on position.
7. no chimes when the key is in the ignition.

Thanks in advance for any advice.

i would start with a test light..     and the owners manual.. checking the fuses in the dash board.. and in the box under the hood...

you might also want to check the relays and other circuits that they have not gotten flood damage.. or water damage from deep water..

this will really damage cars...

cars newer than 2000 have over 300 pages of wiring diagrams usually.. each circuit is printed out ... and you sometimes need multiple pages to figure out where the power comes from..

its important that you noted the circuits that fail to function as normal..

so turn the key on..  test all the fuses..    you might want to make a photo copy of the 2 or 3 fuses pages from the owners manual.. so you can mark directly on it.. if its got power on both side of the fuse or not..

since its an OBD2 car.. you might want to plug in a scan tool .. read the codes...  google them and post them here.. there are Thousands of different codes..

P0000 codes
C0000 codes
B0000 codes..   warning.. not all scan tools will read all the codes...

a few diagrams to start you off...  hopefully...

please use a digital volt meter.. not a test light...

the second half of the page above..

the door locks. page 1

the door lock switches part 2..

this is the retained accessory power diagram... and is probably the first place to start...

the dome lights...

yep.. thats a LOT of circuits to work through..

start at the fuses.. see if they get power during the proper position of the key..

guess. why there are mechanics..  guess why there are electrical mechanics..

don't be overwhelmed..   print the different diagrams i have listed.. go over them one at a time..

start with the fuses..  with a test light.. everything else needs to be tested with a digital volt meter..   they are under 25 bucks in most autoparts stores..  

be careful what you probe..   you can do thousands of dollars in damage..   you will also need a scan tool...

the harbor freight 98614 is the least expensive  out there that might help..
