1) Front wheel off the ground and front to rear drive shaft rotating is normal behaviour. Its when the front wheels are on the ground and the drive shaft can be rotated you have a problem, but not at the DEM but the angle gear or collar drives.
2) If you can prove the pump is good by use of a 9v radio battery, the oil in the DEM is clean, the solenoid can be seen to operate again using a 9v battery, the "fail" points are basically down to two items - Pressure switch or DEM failure.
I have read instances of both.
However,
the DEM unit is located in an exposed position and appears to be susceptible
to water ingress. I would get your DEM checked out before spending more money, and if you intend keeping the car get a DICE/VIDA setup.
Good luck
