Hi,
When you first turn the key to the on position, the pump should prime for a second or two then stop.
Fuel will not be sent again until the PCM recognizes ignition and the engine starts.
Let me know what is happening. Are you able to get it to run at all?
Let me know.

This can be caused by the ignition module failing, I would see if there is spark. This video can show you how:

Also, check all fuses to see if any are blown, here are the locations and how to change out the ignition module in the images below in case you need it.
