Engine problems

Fault

Possible cause

Remedy

Engine does not
start

Fuel tank empty

Fill tank and bleed the fuel system

Battery defective, discharged or not con-
nected

Tighten the terminal clamps on the bat-
tery, check all cable connections.

Starter defective, cable connections on
starter loose or corroded

Check cable connections, have starter
checked by a specialist

Fuel filter clogged, in winter due to paraf-
fin separation

Change the filter, use winter fuel

Fuel lines leaking

Check all line connections for leaks and
tighten the fittings, bleed the fuel system

Air in the fuel system

Bleed the fuel system

Fuel lift pump defective

Have fuel lift pump examined by a special-
ist

Incorrect start of commencement

Have injection pump examined by a spe-
cialist

Engine solenoid not working

Have examined by a specialist, replace if
necessary

Wrong engine oil for operating conditions

Change oil and oil filter, use recommend-
ed type of oil

Engine does not
start and diag-
nostic lamp
flashing

Engine electronics prevent starting

Check fault by fault code, repair as neces-
sary
