Fuel pump running with truck off

I just walked past my 2018 after it's been off for around 8 hours. I heard a slight humming electric motor sound. I didn't crawl under it but I'm pretty sure it was the fuel pump. I started the truck. Ran it for around 10 sec. After turning the ignition off, the pump was no longer running.Is this somehow normal?

Fuel is sitting at around 1/8 tank

 

Yes normal

 

Thanks for the quick reply. What is the reasoning?

 

The truck is doing what I assume to be a self check.

 

Yes, it’s the evap system. It’s in the manual if you want to read the details. I can’t remember off the top of my head. It has something to do with vapors or fumes after its sat for a few hours.

 

EVAP system operating. It's normal.

I didn't even bother to search for other posts because it seemed so odd.

 

Yeah this question has popped up on the forums frequently over the past 16 years since they started doing the EVAP checks in the 2005 Tacoma MY.

 

Huh. Had the same thing happen to me a month or two back, mildly freaked out and cycled the ignition like you. Good to know it's an evap check.
