Mastervolt Whisper Ultra 6 won't start

I'd greatly appreciate advice from anyone who has had a similar problem.

Unit has been lightly used, about 100hrs but has stood for about a year. Keep getting "failure to start" on mastervolt control panel. Engine turns over but does not even try to fire when start sequence begins.
#have installed a new start battery... voltage drops from 12.7 to about 11.9V when cranking so its not a start battery problem.
#oil level is OK.
#have bled fuel and checked that there is no air in the system. Fuel is from main tank and main Volvo engine runs perfectly so not a fuel problem. Fuel lift pump is working fine.
#checked glow plugs (removed them to see if they heat) and cranked the engine with them out. Definitely fuel being injected into cylinders.
#checked visually fuel solenoid is energising by removing cover,
#checked exhaust temp, engine temp and oil pressure switches are all normally closed.
#disconnected air intake hose to make sure no air blockages.
#have not done a compression test because I cannot find what glowplug adaptor to use for the test. In any case if one cylinder had a problem, the others would try to fire?

So I give up! must be a quirk of these engines?

Could anyone suggest anything else to test for?
I'd greatly appreciate any advice.

Can you put another battery in parallel as crank speed may be too low.
