Turn the key to the on position and lift the air sensor plate a bit and can just hear a bit of a click click towards the front of the car. Hmmmm. Pump was running fine when I did my pressure tests and car has been running since. So I pull the pump relay and hook up my jumper wire/switch like I was going to do tests. Turn ignition to on and pump runs fine (just ran it 1 sec at most). Hmmmmmm.

Good to keep a spare relay in the glove box. Yeah, keep a jumper wire and thin blade too for above purpose.

Try start it again on a cold engine without doing the jumper test prior.
The leaky toilet seat valve can cause your original problem.
