Answer 1

It can, but it would also open more than 1 fuse, You have a 65Amp fuse, 75Amp fuse, 30 Amp fuse, You may have another open fuse in the engine fuse jucntion box, so you need to inspect those, Even if you dont blow a fuse you tend to give the fuses a high resistance,a simple remove and install usually solves this. Without that cam sensor signal the vehicle will not start, Check and inspect your fuses,
