I've been reading up on this and looking on youtube. Everyone I talk to seems to have a different opinion. Here's what I'm hearing:
1.) take the new pump apart and load it with Vaseline (I've also heard this is bad)
2.) Stick it in a drip pan with oil and spin it till it has oil then install its just like changing your oil.
3.) Pull the main coil wire and turn it over till you have pressure
4.) Pull the crank sensor and spin with a drill
Opinions? Or am I just over thinking this?

I just squirt motor oil into the pump before installing. No need tor priming with drill either...that is only necessary for a new engine rebuild when everything is dry. BTW, every time you shut off an engine the oil drains out of the pump anyway so this vaseline thing is a myth. Oil it up and your good to go...start engine and let it idle until pressure builds. Your motor is protected by the residual oil, no different then starting your car after it has been sitting for several days.

Disconnect the CPS. Crank the engine over til you see pressure on the gauge. That's a matter of seconds. Plug CPS back in. Fire it off.
