HI i am new to this site i have a problem with my 92 eg6.

I had let my car sit for two days while it was raining and thundering my passenger window was open and it looks like inside my car got wet i dont know if some wires got wet or my computer.

But when i try to start my car in wont start all it does it turns on my fan radio and al my electronic components. i checked my started and it cranks up when i do i do manually by hand and able to drive it but if i turn it off i wont be able to turn it back on . i dont know what it could be i changed my ignition cables and stuff. o and it wont start even when i jump start with jumper cables. um any advice would be good plz

dont know if this helps but
