ok so my car got water damage. very slight.
now it wont engage starter.
tested battery power.. good
tested signal wire no power.
then i checked all the fuses. good. power on both ends.
then i noticed when i turn the key to on position,
the check engine light stays on and the d4 light stays on
in the shifter light section

i have scanned the computer but it wont comunicate with the ecu.

 

Sounds like it's still got an electrical problem or two with the ECU

 

WATER DAMAGE AS IN????

since it's an auto, check the nutrual switch, can you still bring the shifter down to all gears?
