Larry,If low compression or no compression on a cylinder or 3 is the situation with this car, wouldn't it be obvious due to the sound of the starter? When it's coming closest to starting, it sounds like it's catching on 3 cylinders out of 5. I do have a compression tester. This may be the best way to assess the condition of the engine if he'll let me do it.
