Did you fill the oil filter up with oil before putting it on.??
Used to put vasoline on the veins of the oil pump to aid initial pick up of the oil too.

Did you fill the filter (or at least wet it) with oil before refitting?
I know its a problem with some oil pumps (not sure about the crossflow - thinking of Rover V8) that they need priming before they'll be able to
suck oil up themselves.
Another one to check - even the smallest hairline crack will cause a vacuum leak on the pick up pipe which will prevent the cold, thick oil getting
sucked up by the pump
Long live RWD...

I had the same problem when I first started my rebuilt x-flow. What's even more worrying was that I'd just fitted a new cam &
followers, and cranking the engine endlessly is a good way to screw them up!
1. Take the plugs out, so the engine can spin faster.
As Craig said,
2. Smear some vaseline in the pump chamber.
3. Fill the oil filter to the brim before fitting it to the pump while it's OFF the engine.
4. THEN fill the pump chambers up with oil BEFORE fitting it to the block (messy, but it seemed to help)
Start cranking!
Also, make sure that your oil switch and/or pressure gauge is really working - you might have pressure after all!

Glaringly obvious, and sorry to mention it, but you did put oil in the engine as well? Im guessing you have.
Other than that, have you had the head off? It may be the gasket is fouling the oilways?
Check the water, to make sure theres no oil in it. If there is, then you have a nackered block.
Pickup pipe is blocked? I dont know the xfklow, but i would guess its in the sump. Maybe take this off and have a look. If the engine has been
sitting for 10 years, then it has probably hardened slightly or emulsified.
Other than that, throw it away and get a bigger engine!
Kindest Regards,
Richard.

Possibly a stuck oil pressure relief valve? if the pump will pump oil when it's off of the engine it should already be primed . Did you fit a
new seal/gasket on the oil pick up pipe? If all else fails then take the filter off then try cranking . Bit messy but if you get oil out of the pump
refit filter. Not an ideal way of doing things I know but I once had problems with a VW engine and that was the only way that worked.

Take the oil pressure switch or gauge sender out of the block, then back fill the pump through there using a pump oil can and a bit of rubber pipe to
seal it against the block.
That will fill the oil galeries and the pump, refit the sender, next crank you should have instant pressure, and minimal mess, and no pump gasket to
replace.

If I remember from my 1600 x-flow days, I took the distibuter out and used an electric drill to turn the pump as it is directly below the
distributer.
Remember to mark which position your rotor arm is first.
The high reving drill will help move the oil.
You can use an old distributer drive or a bar with a screwdriver type blade to turn the slot in the pump drive.

I believe that you're thinking of the Pinto - in the x-flow the oil pump is driven straight off the cam via a worm gear (the cam's near
the bottom of the block).
