Fuel system: Fuel pump priming every time
 
Hello there,
Recently I noticed my fuel pump was priming every time I opened and closed the driver door. It doesn’t matter how often or quick I open the door, it primes every single time. It also does it when I close the door which I find unusual.

I started noticing this after lubricating the driver door hinge with WD40. I am thinking I may have fried some electronic sensor, but I am unsure what that would be..

Car runs fine and I have no fuel pressure faults at this time. Any help appreciated! :)

That is by design, all normal.
