Take the spark plugs out and Pull the fuel pump fuse so it doesn't get any fuel. Crank on it for like 8 seconds at a time for a few times. That gets it primed good.

I just hold the pedal down and crank for a few seconds. Do it a few times. I do this every time I change the oil.

I cranked it over enough to drain the
Battery yesterday with fuel pump turned off
Still no oil pressure so I took the oil filter off
And cranked it over a couple times no oil
Came out of the filter hole I don't know what to
Try next

Could always try the bug sprayer method.....I think that's how some of the mod motor guys prime brand new engines.

I think there is a vid on YouTube.

yea, some people do the bug sprayer method. A quick search says most agree with cranking it over first and its fine. It wont build much pressure but enough to get oil on critical parts

That's why I take the plugs out so there no compression on the rods
