Beta diesels are very reliable if installed and serviced correctly, but problems can occur and the following list gives the
most common ones and their solution.
Problem: Engine does not start but starter motor turns over OK
Possible Cause Solution
No fuel: Turn fuel cock on and fill tank.
Air in fuel system: Vent air (please refer to ‘Initial Start-up’ on page 21).
Water in fuel: Change fuel filter, check fuel/water separator
and bleed system.
Blocked fuel pipe: Clean out and bleed system.
Fuel filter clogged: Change filter and bleed system.
Fuel lift pump blocked: Remove and replace.
Blocked injector: Remove and clean.
Fuel return not fed back to the tank: Re-route fuel return pipe.
Heater plugs not working: Check wiring to the plugs, and replace plugs
if they are burnt out.

Problem: Starter motor will not turn or turns over very slowly
Possible Cause Solution
Battery discharged: Charge battery or replace. Check alternator belt tension.
