Step 5.
Disconnect supply fuel line at water pump engine fuel rail (WP 0234). With a pressure
gauge, check for 16 psi (110 kPa) fuel pressure at supply fuel line which was
disconnected from water pump engine fuel rail.
If 16 psi (110 kPa) fuel pressure is not present, replace secondary fuel filter
(WP 0231) and go to Step 6.
Step 6.
Replace fuel/water separator filter (WP 0238). Replace secondary fuel filter
(WP 0231). With a pressure gauge, check for 16 psi (110 kPa) fuel pressure at supply
fuel line which was disconnected from water pump engine fuel rail.
a.
If 16 psi (110 kPa) is present, fault corrected.
b.
If 16 psi (110 kPa) is not present, replace water pump engine fuel
pump (WP 0236).
