I have been having some very strange electrical problems . Power to the fuel pump comes and goes. The Radio and interior lights have no power. I have looked at fuses and relays although it is hard to tell which relays I should be looking at in the relay jungle. Any info will be helpful.

 

Grounds and clean all connectors then use dielectric grease. Make sure your ground strap connection is not corroded. this mean remove ground strap clean apply dielectric grease reconnect. make sure alternator is working. Clean contact on ECU etc.
