Correct me if i'm wrong, but doesn't this engine have glow plugs? Glow plugs can be removed, and the compression adapter screwed in to check the compression. A diesel tester can be rented at many auto supplies are Harbor Freight sells one for around $50.00.

Just have fuel solenoid disabled so engine does jot start, check one cylinder, then the next, check all to see if all are same. Looking for reading near 400 psi.
