Dodge Durango 99 5.2l.

Checked everything.  
Wiring harnesses are
craps. The plug INS to
the pcu are aluminum
if you live any where
close to the ocean
they oxidize and fail.  
The pins that plug in
to pcu will crumble
apart making. For a
weak or no
connection. Plus any
heat damage will
cause the insulation to
crumble and oil leaks
around valve covers
cause a short which
can fry your pcm no
matter if it is new or
old. Dodge slapped
them together with
plastic green boards
