When ign switch is off - no fuel....

No good! There should only be fuel when the engine is cranking (to start),
or there is oil pressure (engine running). The latter could save your engine
as well. If the oil pressure drops for any reason, the fuel pump will cut
out, and the engine will stop before you melt the block. If the ign switch
is simply on, and the engine isn't running, the fuel pump should NOT be
moving fuel.

How did you power the electric fuel pump? In the event that you didn't
....
consider providing it's power in a manner that the power is removed if the
engine is not running, even though the ignition may be "on". Often, this
is
accomplished by powering it through an oil pressure switch.
