9. Use the microprocessor keypad to enter the Relay
Board Test Mode. Refer to the appropriate Micropro-
cessor Operation and Diagnosis Manual for detailed
information about the Relay Board Test Mode.
10. Energize the fuel solenoid by energizing the run relay
[RUNR] with the Relay Board Test Mode.
11. Rotate the engine backwards (counterclockwise viewed
from the water pump end) until the injection timing
mark is positioned in the bottom of the timing mark
access hole. The injection timing mark is a horizontal
line stamped on the flywheel approximately 1.2 in. (30
mm) before the top dead center mark.
12. Pump the priming pump by hand a few times, or ener-
gize the electric fuel pump if an electric fuel is being
used.
13. Use a clean towel to remove the fuel from the top end
of the delivery valve holder.
14. Slowly turn the engine in the normal direction of rota-
tion until you see the fuel rise in the end of the delivery
valve holder. Stop as soon as you see the fuel rise.

15. Check position of the timing marks. The injection tim-
ing mark on the flywheel should be aligned with the
index mark on the side of the timing mark access hole.
Repeat steps 11 through 15 to recheck the timing.
16. If the timing is off by more than 1 degree (0.1 in.
[2.5 mm]), loosen the mounting nuts on the studs that
fasten the injection pump to the engine and rotate the
injection pump to change the timing.
a. Pull the top of the injection pump away from the
engine to advance the timing.
b. Push the top of the injection pump toward the
engine to retard the timing.
17. Tighten the injection pump mounting nuts and recheck
the timing. Repeat steps 11 through 17 until the timing
is correct.
18. Install the cover in the timing mark access hole, install
the injection line for the number one cylinder, install
the rocker arm cover, and tighten the other injection
lines when finished with the procedure.
