I'm sure it can be.

I can't be positive on the Neon, but it's not a good idea for the
fuel pump to just run continuously with the ignition in the "on"
position. If you were in a wreck and the fuel line was severed,
would you want the fuel pump to keep running? I think the fuel pump
shuts off after about two seconds if the engine is not running. If
you were to turn the ignition "on," you would probably hear a
humming sound for a couple of seconds and then quiet. That would be
the fuel pump running to build up fuel pressure and get the engine
started and shutting off when there is no ignition signal.

Probably, but what makes me uncomfortable about this is most fuel
injection high-pressure, high-volume fuel pumps are cooled and
lubricated by the gasoline. Best case scenario: nothing happens and
everybody is happy; worse case: the fuel pump burns up and has to
be replaced. Even if everything seems ok, you could shorten the
life of the fuel pump. This happens sometimes when people run out
of gas; they try to start the car for a few minutes before they
realize they're out of gas. But later it still won't start because
the fuel pump is burnt up and has to be replaced. I don't even
think it's a good idea to run a car low on fuel because of the
possibility of sucking air while cornering and damaging the pump.
>Thanks in advance.
Sure, just want you to know all the possibilities.
