Simply bypassing a fuse is not a good idea without putting another fuse in its place to prevent an over-current condition, and the wiring harness burning the truck down if something shorts out.

Are you sure it is not the clutch switch acting up and not allowing it to crank?.

Maybe some history of the issue, better descriptions of when it started acting up, and what has been done so far?.

Maybe this article helps...
