ON−VEHICLE INSPECTION
1. CHECK THAT SPARK OCCURS
(a) Disconnect the high −tension cords (from the ignition coil)
from the distributor cap.
(b) Hold the end approx. 12.5 mm (0.50 in.) from the body ground.
(c) Check if spark occurs while engine is being cranked.
HINT:
To prevent gasoline from being injected from injectors during
this test, crank the engine for no more than 1 − 2 seconds at a
time.
If the spark does not occur, do the test as follows:

NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10° C
(14 °F) to 50° C (122°F) and ”Hot” is from 50 °C (122° F) to
100 °C (212 °F).
