Let's confirm which fuse is blowing. Is it fuse 21 in the PDC?

If it is then this issue is due to something drawing too much current. So either the relay is stuck causing the fuse to blow or the fuel pump is shorted causing the issue.

What I would do is swap the relay with another and retest the issue. If it blows another fuse then I would replace the pump.

I attached the process below for each of these. Please let us know if you have other questions and what you find with this. Thanks
