I have had a compression test done on a 75 hp Volvo. The injectors are removed and the test pressure gauge is attached to the hole for each cylinder at a time and the engine turned over by the starter. The whole process took less than an hour. The test gauge does have to fit the particular engine but Volvo agents should have access to this equipment.
I feel for you in your trouble. Funny isn't it. If you have a car you take it to a repair garage and they fix it. Our boats with modern engines seem to be beyond the skills of the repairers and yet they are the same engines as cars. I guess our engines are in a much harsher environment of salt air and moisture. That's why I suspect the electronics

The Volvo guy did not do a compression check, but did suggest that would be the next recommended step. After studying the Volvo Penta D3-110 service manual, my assessment is that getting access to do a compression check is not easy. Plus it requires test equipment. Have you seen one performed on that engine? Was it expensive?

Hi Jamie. He "thinks" the compression may be low. I am totally cynical about this. Did he do a compression test, a very standard test that takes little time given the correct equipment. I would suspect a fault in the electronic "clevers" that don't allow fuel until the electronic checks are done and "requirements" met. In any event I would not proceed until a compression test is done. The results do not have to be perfect, an engine will start with one cylinder totally lacking compression, and will start with varying compressions but obviously not if they are too low.

I want to thank everyone for the great advice and suggestions regarding my Amel 54 (Phantom) engine "no-start" issue. Since no one has been able to pinpoint the problem, I just had a Volvo Penta factory technician out to survey the situation. He thinks the compression is low on the engine, as it would not fire even as we sprayed WD40 into the intake. Although he had no specific rationale as to the possible cause of this conclusion, he did suggest that earlier fuel-starvation could have caused the problem, stressing the importance of maintaining a clean fuel supply at all times.
I have decided to replace the engine. That will restart the clock with zero hours and a 5-year warranty. The alternative would be to start tearing down the engine to determine the problem. Even if we do find something (blown head gasket, stuck valves, scored cylinders, etc.), chasing this "rebuild" tactic would be a very expensive and time-consuming operation - and it will still be a 9-year-old engine with 2500 hours. Although hugely expensive, a new engine is the only rational option. I do not want to continue chasing "ghosts."
Thanks again for the support.
