Or doesnt that work?

Please tell me! I might run out of gas someday.

When the key is first turned on, the pump is only run a couple of
seconds to be sure the fuel rail is up to pressure. The pump isn't
allowed to run continuously unless the engine is actually running or in
the process of being cranked.

It's a safety thing, you don't want the pump running alone... if allowed
to do so, it could pump the tank contents out through a ruptured fuel
line at an accident site. It happened more than a few times back in the
early days of electric fuel pumps.

Ah! Thanks!

So If the schrader valve is pressed and held down...then the ignition
turned on and off repeatedly...it should bleed?

It's done several ways, and some also incorporate inertia switches in
the fuel pump power lead.

They all have a way to override this feature in order to quickly bleed
the system and do pressure/flow tests, but your not likely to have the
proper scan tool, jumper wires and/or whatever on the cold rainy night
you need to do a re start. The override procedure is in your shop manual.

PS, Also be aware that not all cars are equipped with fuel service
ports... in which case there is no Schrader valve to push.

Ok. Never saw one without..but then Im not a big car guy.
