Silverado won't start. Had same problem.previpisly. Replaced

Customer Question

Silverado won't start. Had same problem.previpisly. Replaced battery, starter, checked fuse box, etc... with they ignition key turned I was fiddling with the engine compartment ignition fuse, it sparked and the vehicle started and no issues for months. Today while driving I turner the AC fan to 5 and the fan cutout, dash warning lights came on but vehicle remained running. Got home and parked the truck and tried to start it - nothing. Tried pulling and reinserting the eng comp ignition fuse with key turned and it almost turned over once. ( this fuse had previously been replaced when troubleshooting and the fuse itself is joy the problem / possible a short?)

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 ?

Customer: replied 3 months ago.
V8 engine ... Battery, connections wires and starter are not the issue. The fuse in question is the engine compartment ignition fuse ... #5 on the fuse box legend. Large square fuse with 4 prongs. Delphi 8864.This was the culprit months ago but the actual issue was never diagnosed, the truck just started when removing and reinserting it.

Expert:  Gary replied 3 months ago.

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 ?

Customer: replied 3 months ago.
I have interior lights, power locks , headlights... No radio, fan, ignition.With the key turned if I remove and reinsert the fuse there is flatly and clicking in engine (fuel pump?) and the nothing. Once when doing this there was a partial crank.
Expert:  Gary replied 3 months ago.

are any of the terminals black or brown on the relay showing the terminals are arcing ?

Customer: replied 3 months ago.
Not seeing that , no
Expert:  Gary replied 3 months ago.

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
