Fuel pump runs when truck is off

Walked out in the garage more than once and have heard the fuel pump running on my 2009 Tacoma. Any ideas? Relay or pump problem?

 

I think it's not a problem.......

Love how that link takes you to another link

 

I've got a RC '13 two weeks old and have heard the same noise twice now. When I put the key and turn it to Acc. it stops. WTF???

 

Ok, I guess I should have read the link first... I guess it's nothing new, but this is my 1st Toyota, so it's new to me.
"It's not the fuel pump. It's the vacum pump in the evap system. It pulls a vacum in the fuel tank and related hoses and then checks for leaks......"

 

Yeah, my 13' does it

 

It's because your tacoma doesnt want to stop. It wants to keep driving!

 

Should typically happen 4-5 hrs after shut down. If you have a manual, it states this is normal, and when and why it happens.
