2000 F150 Triton v8

My truck was setting for awhile and had a leaky
back window I didn't know about until I noticed it
had condensation inside windows I opened the
door to find it had started to mildew the carpets
and seats. Fixed leak but it want crank windows
don't work power seats don't work. It's not getting
fuel to the fuel rail , never hear fuel pump even try
to start. I'm no good with electronics.  I was told to
try replacing the body control module. Kind of a
expensive try. So any advice would be helpful.
