Fuel Pump Reset Switch?

I have an 2007 R350. Through my own stupidity and stress, I let it run out of
gas. Not a problem one before this. After filling it up, it would not start even
though it turns over great.

I cycled the key and nothing. I also checked the bleeder valve on the fuel line
and there was no pressure although I can hear the fuel pump turn on when i
turn the key. I additionally checked the fuel canister shut off under the
passenger side tire well and it was in the open position.

At this point I am thinking there must be a fuel pump shut off reset
SOMEWHERE!? However, I cannot find ONE THING about this online!
There are those that ask the question and then it goes off on an ADD
tangent about other things and no one has shared (that I have found) where
it is located if there is one at all?

HELP!!!
