I did pull the shaft and inspect it, it's in perfect condition. I stuck the priming shaft down there and spun it....nothing. Priming before break in I had to hold the drill with 2 hands and it still tried to twist my wrists.View attachment 1312134
Relief valve could be hung open or a dozen other possible problems... A lifter out of it's bore, oil pump found a way to suck air, oil pump drive shaft sheared...
In your post you say "Intermediate shaft, no issue, gears just like brand new." did you actually pull the shaft & inspect it? Or looked & saw the gears look good? Cause twice I've seen the drive hex get sheared off...
Have you tried spinning the oil pump with a priming tool?
