INSPECT IGNITION COIL (WITH IGNITER) AND
SPARK TEST
Check that the spark occurs.
(1)
Remove the ignition coils (with igniter).
(see page
(2)
Remove the spark plugs.
(3)
Install the spark plugs to each ignition coil (with ig-
niter), and connect the ignition coil (with igniter) con-
nector.
(4)
Disconnect the 8 injector connectors.
(5)
Ground the spark plug.
(6)
Check that spark occurs while engine is being
cranked.
NOTICE:
To prevent gasoline from being injected out of injectors
during this test, crank the engine for no more than 5 to 10
seconds at a time.
SPARK TEST
Replace the crankshaft position sensor.
