Engine does not start
(starter motor cannot crank engine at normal speed or starter motor does not function at all)

Possible fault

Poorly charged battery or flat battery.




Poor contact at the battery or starter motor connections.


Fault in starter motor.
Fault in ignition switch.

Action

Hand in the battery to charge station for charging or fit a new
battery.

The car may possibly be started by towing or with the help of an
auxiliary battery (but find out the reason why the battery is flat).

Clean the cable terminals and tighten up the pole shoes and all
connections.

Let a Volvo workshop carry out repairs.




Engine does not start
(althoug the starter motor cranks engine at normal speed)

Engine does not get any fuel.                                                





Water or dirt in the fuel

Fault in ignition system.






Fault in injection system.
Check to see if there is fuel in the tank and check lines up to
engine.

Check tomake sure that fuses No 5, 7 and 13 are functioning
properly (see page 54).

Empty and clean the tank.

Check spark plugs (electrode gap, cracked insulator, etc.)

Check distributor cap for cracks or other damage.
Check all electric cables in the ignition system to make sure they
are properly connected and that they are clean
Check the ingnition coil.

Let a Volvo workshop carry out repairs.

Clogged fuel filter.

Faulty firing.

Exhaust gas recirculation valve does not function.

Check air cleaner.

Replace fuel filter. (Carburettor engine clean filter)

Check.

Let a Volvo workshop carry out repairs.


High fuel consumption

Leakage in fuel system.

Poor spark plugs.

Clogged air cleaner.

Fault in carburettor or in injection system

Put right.

Check and if necessary replace spark plugs.
