NG -- REPLACE SPARK PLUG See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Removal
OK -- Continue to next step.
8. CHECK FOR SPARK AND IGNITION (SPARK TEST)
(a) Perform a spark test.
CAUTION:
During the test, disconnect all fuel injector assembly connectors.
NOTICE:
Do not crank the engine for more than 2 seconds.
(1) Remove the ignition coil assembly from the cylinder head.
(2) Install the spark plug onto the ignition coil assembly.
(3) Disconnect the 6 fuel injector assembly connectors.
(4) Touch the spark plug to the cylinder head.
(5) Crank the engine for less than 2 seconds and check for spark.
OK:
Spark jumps across electrode gap.
(6) Reconnect the 6 fuel injector assembly connectors.
(7) Reinstall the ignition coil assembly.
NG -- CHANGE TO KNOWN GOOD SPARK PLUG AND CHECK SPARK OF MISFIRING CYLINDER
OK -- Continue to next step.
9. CHECK CYLINDER COMPRESSION PRESSURE OF MISFIRING CYLINDER
(a) Measure the cylinder compression pressure of the misfiring cylinder See: Engine, Cooling and Exhaust/Engine/Testing and
Inspection/Engine.
NG -- CHECK ENGINE TO DETERMINE CAUSE OF LOW COMPRESSION
OK -- Continue to next step.
10. CHECK FUEL INJECTOR ASSEMBLY (POWER SOURCE)
(a) Disconnect the fuel injector assembly connectors.
(b) Turn the engine switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
