The ECM primes the pump on key on for ~5 seconds, unless you change it, then it will turn the pump on again once it sees crank signal. This is so if there is an accident situation and the engine stops, the pump shuts off so it doesn't pump fuel onto the ground until the key is shut off.
You could have the initial prime set to like 15 seconds so you have more time to hit the button for crank.
