4.3.5. DE12TIS fuel injection pump inspec-
tion & adjustment only
1) Pre-stroke actuator inspection drive
shaft.
Replace the drive shaft if the ball section
is bent,worn or damaged.

2) Electrical components
(1) Check the resistances between the
prestroke actuator terminals shown in
the figure at left using a circuit tester.
Their resistances are shown below.
Also, check that the resistance
between the terminals and the hous-
ing is
∞.
Terminal Resistance(
Ω)
1~2 2.45~2.95
3~4 5.5~6.1
5~6 5.5~6.1

(2) Check the conductance between
each of the pre-stroke acuator termi-
nals and connectors using a circuit
tester.
COUTION : The connector ter-
minal layouts and
shapes differ with
maker and engine.
