Well my PI stopped working and/or was getting flaky. It was happening more so when it was cold out "freezing temps" and I was not sure if it was a pump issue or something else. I took the bumper off and tested the pump which worked without issue. I checked fuses and everything was good. So I decided to check the relay.
Turns out it is not very waterproof..... I did have it mounted so that the wires were up so maybe the water was seeping through that. I am very surprised it was working at all.

I ended up changing location and flipping relay so it is pointing down. I cleaned up the harness and put a new relay in there. Fired right up.
