A fusible link? For a ground wire? This TSB is saying to clean and retighten all the grounds.
A test light will be good enough for now. With this bulletin, the grounds are the most concern. But we will need to check everything until we find the issue here. Check on the passenger side foot well for grounds, they might be behind the glovebox or the lower panel where your right foot would be. The engine computer is on that side too.
These are the ECM power locations, The Fuse panel on the driver's side dash, fuse number 1 10amp is powered up at Key On should be hot on both sides.
The second diagram is the ECM relay, if you pull the relay out, 2 out the of 4 pins should have power even with the key off. Fuse 35 in the Power Distribution module powers the ECM relay.
The 3rd diagram is the ECM memory fuse. It's fuse 35 also, hopefully these diagrams are correct,
As for your question on the cam crank sensors, they are both Hall Effect 3 wire sensors. The cam sensor detects where the number 1 cylinder is, the description says the vehicle can actually run without the crank sensor, I'm sure they are referring to after the vehicle is started.
But with no check engine light, nothing is going to be powered up. The sensors are powered by the ECM.
One thing you can try is if you have some jumper leads, you can run a ground from the battery negative to the engine block and also to the frame(body) and see if anything changes, just as a very temporary test. If the check engine light comes on, or it starts, we'll know it's a bad ground.
