So, installed the replacement F9 SSR. As a reminder, this one has the Pump-Prime feature automatically runs the fuel pump for up to 3 seconds when the ignition is switched to the "On" position. Week later, battery completely dead again - like so dead it will never come back which is indicative of power going to the relay I installed and it basically priming the pump or something until all juice is out of the battery.

I've never had this issue with my OEM Relay and while I know that I can just install it and leave well enough alone, the cats out of the bag and there MUST be power going to the Relay even when the ignition is off and key is out. Nothing else is on in the car and again, with the original one, never had an issue with the battery.

Any thoughts on what could be happening here? I don't think the F9 is the cause of the power just reacting to it and draining the battery.
