The IP should draw enough to run, even down the highway. At least this was true for me with a non-functioning mechanical pump. I drove around for a month or two with a bad mechanical lift pump. The electric pump might be different.

The pump will only typically run for 3 secs after you turn the key on if you do not start the engine. You might be able to hear it as a slight whine. If you have the air bleed valve open, and cycle the key, you should see fuel come out if the system is primed and the pump is functional.
