Guys, he's saying it starts better if you start it like a gasser. If he starts it while it has fuel pressure it starts better than when it drops back down to 0 after the pump kicks off.
On my truck it doesn't make any difference if there's pressure or not, it starts quick either way. I'd say if it starts better like that then keep doing it.
Could you possibly have a slight leak where some air could get in and with the pump running it gets it out, but when it shuts off it gets in there and makes it start a little harder? Just a thought.
