Cat M50D no lift

Hi everyone! Got an issue where this machine won't lift. everything ohms to the card good. No P contactor pull in. PS ramps the pump so I'm assuming the transistor and the diode are both good. Anyone got a book? SN is 6GC01293. I suspect the lift valve card but not 100% sure.

Thanks!

bring a magnifying glass, if I remember correctly, the table that tells which is what should be in the corner of the decal of the schematic that was on the door when you open the controller compartment,
Is this is one with an 'LDC', controller?

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
