which exact fuse where you touching ? can you upload a picture of it ?
and BOTH battery cables are clean and tight at the battery and where one power wire bolts to the under hood fuse box that is clean and tight ?
what size engine is in this truck ?
which one here ?
this is a 2001 1500 pick up with a 5.3 engine in it ? the picture i sent you was for a 2001 your box is alot different
ok good that is the relay called IGN 1 it powers most of the circuits
right now if you wiggle it will any power come back ?
are any of the terminals black or brown on the relay showing the terminals are arcing ?
what you have going on and it common with these fuse boxes are usually terminal internal issues that will cause bad connections on the relays or internal in the box the circuit boards go bad
there is no way to take them apart to repair them if the relay is new and the terminals in the box are making a good connection to the relay terminals then i am sorry to say the under hood fuse box would need to be replaced
