ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK SPARK PLUG CONDITION.
1) Remove the spark plug.
2) Check the spark plug condition.
Is the spark plug status OK? Go to step 2.Replace the spark
plug.
2CHECK IGNITION SYSTEM FOR SPARKS.
1) Connect the spark plug to ignition coil.
2) Release the fuel pressure.
3) Contact the spark plug thread portion on
engine.
4) While opening the throttle valve fully, start
the engine to check if spark occurs at each cyl-
inder.
Does spark occur at each cyl-
inder?
Check fuel pump
system.
