Corrosion inside fuse?
Zoom in and you can see the corrosion on the 30 and 40 amp fuse
Has anyone ever noticed corrosion inside the fuses located in the engine fuse box?
I looked at mine yesterday and they have small amounts of green looking corrosion on the filament.
truck has had issues starting and wondering if this could be a culprit.

Pull them out and inspect. 80-Amp is Fusible Link module. Don't force it. it screws into terminals in bottom of fuse block.

It has been slow to get started over the last couple of weeks but now there’s no start at all. The 30a and 40a check out with 0 resistance, but I haven’t pulled the 80a out yet.

It cranks, but no start. The cranking sounds healthy it just won’t catch. Checked for fire at the coil and got white/blue/orange spark. I know I still need to check the other side of distributor.

Pls search fuel pressure gage piggybacked on CSI for positive indication of fuel pressure.
Terry has write-up on how to remove 80-amp FL.
Looks like this from below:

thank you. I’ve been trying to find some info on checking the fuel on 3VZE. I will check the write up for the 80a fuse

I did go out and listen for the fuel pump. I could hear it kick on, and it ran for a good 15 seconds before it shut off. I thought it was only supposed to kick on for 2-3 seconds
