In my boat I have a 6 year old Webasto 90S diesel heater with 1,400 hours. For the past six months I have had an intermittent problem where it will fail to start giving an error code of fuel delivery issues. I have had a certified mechanic take the unit apart, inspect and clean it as needed, and it will work for a few cycles but then fail with the same error code. The filter has been changed and the fuel line from the main tank checked for leaks. I always use ValvTect diesel and the Raycor on my engine has shown no signs of water intrusion or other contaminants.

Any pertinent experiences or ideas would be welcome.

Thanks.
 
You should try and contact a local Webasto dealer/ service center for the unit. This might require a Webasto certified technician. If possible can you test the unit using a small portable fuel source? It sounds as if it is starving from lack of fuel when trying to cycle.
