If any resistance is not good, replace ignition coil.
If the windings test good, try a new ECM.
NOTE:
Prior to inserting the ignition coil to its lo-
cation, apply some silicone lubricant (P/N 293 600
041) as shown. After installation, ensure the seal
seats properly with engine top surface.

WARNING
Never remove ignition coil from the spark
plug without disconnecting it from the wiring
harness. Flammable vapors may be present
in the bilge and ignited by a spark which
could cause an explosion.
Disconnect the wiring harness from the ignition
coil.
Remove the ignition coil.
First unscrew the spark plug one turn.
Clean the spark plug and cylinder head with pres-
surize air then completely unscrew.
Spark Plug Installation
Prior to installation make sure that contact sur-
faces of the cylinder head and spark plug are free
of grime.
1. Using a wire feeler gauge, set electrode gap
according to the following chart.
2. Apply anti-seize lubricant over the spark plug
threads to prevent possible seizure.
3. Hand screw spark plug into cylinder head.
Then, tighten the spark plug clockwise an
additional 1/4 turn with a proper socket.
