CORRECTIVE ACTION
4. Start engine (TM 5-3895-385-
1. If engine starts and fuel
10) and idle, or if engine fails to
pressure range at fuel filter inlet
start, measure pressure while
is between 73 psi (503 kPa) and
cranking.
189 psi (1303 kPa), record
pressure, turn keyless engine
switch to OFF position (TM 5-
3895-385-10), restore
equipment to original condition,
and go to next test.
2. If engine does not start and fuel
filter inlet pressure at engine
cranking is between 44 pounds
per square inch (psi) (303
kiloPascals (kPa)) and 160 psi
(1103 kPa), record pressure,
turn keyless engine switch to
OFF position (TM 5-3895-385-
10), restore equipment to
original condition, and go to
next test.
3. If engine starts and fuel
pressure at fuel filter inlet is not
between 73 psi (503 kPa) and
189 psi (1303 kPa), turn keyless
engine switch to OFF position
(TM 5-3895-385-10), and
replace fuel pump (WP 0329,
Vol 2).
4. If engine does not start and fuel
filter inlet pressure at engine
cranking is not between 44 psi
(303 kPa) and 160 psi (1103
kPa), turn keyless engine switch
to OFF position (TM 5-3895-
385-10), and replace fuel pump
(WP 0329, Vol 2).
5. Remove pressure gauge and
adapter and connect fuel filter
inlet line to fuel filter head.
Disconnect fuel filter outlet line
from fuel filter head. Attach fuel
pressure gauge and adapter
(WP 0448, Vol 3, Figure 56).
