Hello, are you referring to the A2-5 (30amp) fuse that feeds power through the 2 Starter Cut Relays? The number 2 Starter Cut Relay is the relay that ends up feeding power to the Starter Motor. But there are a couple fuses involved in this circuit. There is also a Number 2 fuse 7.5amp that is a signal wire to the engine computer, it looks like that fuse is to verify power is coming through the Starter Cut Relay number 1. I'll post diagrams of all this so we can be sure of what fuse you are not receiving power at.
I believe some of these diagrams are mislabeled. Even in the OEM manufacturer diagrams, 5, 6, 7.
In the 4th diagram, which is an aftermarket diagram, fuse 2-5(30amp) feeds power to Starter Cut Relay number1, then to Starter Relay Cut number 2, which in turn feeds power to the Starter via the Red wire. But both relays need to be energized for this to happen. The fuse labelled 5(7.5amp) goes to the PCM on a green wire as a signal that Relay 1 has energized.
Then on the OEM diagram fuse 5 is labelled actually Fuse 2 (7.5amp) which you can see in the last diagram. I think they are both incorrect. But besides that, for now, if you can tell us which fuse you're missing power, we can figure out where it's supposed to come from. There are a number of reasons why it might be missing.
The 1st diagram is the under-hood fuse panel, M2 and M5 are the Starter Cut Relays marked in green, Fuse 2-5 is also marked in green.
