Page 11:75 Service diagnosis

Go To Top of Page.

The diagnosis outlines below is only intended
to serve as a guide to locate and temporarily
correct minor faults. Causes for unsatisfac-
tory performance should be investigated and
corrected by your Volvo dealer.

NOTE: The points indicated by an asterisk
(*) should be checked by your Volvo dealer.



Condition: Starter fails to operate (or operates very slowly)

Possible cause

 Correction

Weak battery or dead cell.




Looose or corroded battery cable terminals.




Open circuit between ignition/starter switch
and ignition terminal on starter.


Starter motor defective.



 With the ignition switch in the "Driving"or "On" position,check to see if the warning lights
on the dashboard come on and if they stay on when starter is engaged.
If the lights do not come on or of they go off when the starter is engaged, the battery is
discharged or see below.

Check battery terminals and clamps. Clean or replace if necessary. Check that the starter
cable is secure at its terminals.
The ground strap, which connects the body to the rear of the engine, should also be
checked for corrosion or looseness.

The circuit is closed if a clicking sound is heard from the starter when it is engaged. If no
clicking sound is heard, check that the blue wire at the starte is secure. If still no clicking
sound is heard, the ignition switch or the wire is defective.

If the above checks have been performed, and no fault is evident, the starter may be
defective.

NOTE: In this case the headlight intensity will not dim when the starter is engaged.

Condition: Starter motor operates but engine does not start

Possible cause

 Correction

Intake system leaking.

No fuel reaching engine.


No spark.





Spark plugs, high tension leads or distributor
cap wet or defective.

Cold start injector defective.

Rest pressure incorrect.


 Check vacuum hose connections at manifold and auxiliary air valve.

Check for fuel in the tank.
Check fuse No 5,7 and 13.

Remove one spark plug wire and unscrew the radio interference suppressor. Hold the
wire approx. 3/8" (10 mm) from the valve cover and run the starter.

If there is no spark, check the high tension lead from the coil to the distributor cap is
connected and that the wires to the distributor and coil are connected.

Clean the parts with a dry or spray with a moisture remover. Replace defective or
worn parts.

Test the cold start injector function with cold and hot engine.*

Test rest pressure and the fuel system for leaks.*

If no fault is found following the above steps, contact your Volvo dealer.
* Should be checked by a Volvo dealer.

Condition: Erratic idle (misfiring)

Possible cause

 Correction

Intake system leaking.

Spark plugs, high tension leads or distributor
cap worn (defective).

Worn spark plugs.

Cold start injector leaking.

Uneven compression.
 Check vacuum hose connections at manifold and auxiliary air valve.

Clean distributor cap and leads, check the cap for cracks. Replace defective or worn parts.


Remove, Clean or replace spark plugs.

Test the injector function.*

Test compression.*





Condition: Engine stalls at irregular intervals

Possible cause
Correction

Defective wires.


Intake system leaking

Low idle speed.

Fuel filter clogged.
 Check wire terminals at: fuel pump, fuse No 5 and 7, coil, distributor, ignition switch and
relays.

Check vacuum hose connections at manifold and auxiliary air valve.

Adjust.*

Clean fuel tank filter and replace fuel line filter.
* Should be checked by a Volvo dealer.



Page 11:78 Service diagnosis
Go To Top of Page.

Condition: Low top speed, loss of power

Possible cause

 Correction

Air filer clogged.

Throttle misadjusted.


Incorrect timing.

Fuel filter clogged		 Check air filter.*

Check that the throttle touches the high speed stop when the accelerator is fully de-
pressed.*

Check amd adjust.*

Clean fuel tank filter and replace fuel line filter.*





Condition: Excessive fuel consuption

Possible cause
Correction

Fuel lines leaking.

Sparks plugs worn

Incorrect timing.

Air filter clogged.

Control pressure incorrect.

Cold start injector leaking.

 Check tightness.

Replace plugs.

Check/adjust.*

Check/replace.*

Check/replace control presure regulator.*

Replace injector.*
(A leaking cold start injector also causes uneven idle and hard starting.)
* Should be checked by a Volvo dealer.



Page 11:79 Service diagnosis
Go To Top of Page.

Condition: Dieseling


Possible cause
Correction

Injector leaking.

 Check air flow sensor plate and rest pressure.*






Condition: Misfiring at highway driving

Possible cause
Correction

Spark plugs fouled.


 Drive the vehicle in a lower gear and keep the engine rpm higher for a few miles in order
to remove carbon deposit on the spark plugs. If this procedure is not effective, clean or
replace the spark plugs.
* Should be checked by a Volvo dealer.
