check the ground busses
#1 behind pass side kick panel (clear connector 5 leads side by side)
#2 front of radiator support on drivers side (same connector)
#3 front of radiator support on pass side (same connector)
look real close for corrosion or melted wires
also check the connector down from neg terminal on battery,
the pins will seperate and cause problems like that.
in extreme cases you will see the wires have bulged and turned black due to high heat.
and last off
check your ground strap from pass side motor mount to chassis
those were insufficent at best.
clean all connections with contact cleaner and remember to pack them with di electric grease to prevent corrosion in the future
hope this helps
