Fuel Flow Actuator Inspection; Fuel Flow Actuator Removal And Installation - Suzuki GRAND VITARA 2005 Service Manual

1G-21 Fuel System:

Fuel Flow Actuator Inspection

Check resistance between terminals of fuel flow
actuator.
If resistance is out of specification, replace fuel flow
actuator referring to "Fuel Flow Actuator Removal and
Installation: ".
Fuel flow actuator resistance
2.9 – 3.1 Ω at 20 °C (68 °F)

Fuel Flow Actuator Removal and Installation

WARNING
!
Before servicing fuel system, be sure to
observe "Precautions on Fuel System
Service: ".
CAUTION
!
• Do not reuse fuel flow actuator and fuel
flow actuator bolt because it has the
possibility that fuel leaks.
• Never leave fuel flow actuator orifice open.
Replace new fuel flow actuator at once in
order to prevent fuel circuit from
contamination.
Removal
S5JB0B1706033
1) Relief fuel pressure referring to "Fuel Pressure Relief
Procedure: ".
2) Disconnect negative (–) cable at battery.
3) Clean fuel flow actuator and its surrounding area.
4) Disconnect fuel flow actuator connector.
5) Remove fuel flow actuator (1) from injection pump by
pulling and twisting it gradually.

Installation
S5JB0B1706032
1) Apply clean fuel to O-rings.
2) Fit new fuel flow actuator (1) to injection pump.
3) Tighten new fuel flow actuator bolts (2) as follows.
a) Tighten fuel flow actuator bolts to 3 N⋅m (0.3
kgf-m, 2.5 lb-ft).
b) Retighten fuel flow actuator bolts to 6 N⋅m (0.6
kgf-m, 4.5 lb-ft).
Tightening torque
Fuel flow actuator bolt (a): Tighten 3 N⋅m
(0.3 kgf-m, 2.5 lb-ft) and 6 N⋅m (0.6 kgf-m, 4.5
lb-ft) by the specified procedure.
4) Connect fuel flow actuator connector.
5) Connect negative (–) cable at battery.
6) Check fuel leakage referring to "Fuel Leakage Check
Procedure: ".
7) Check DTC referring to "DTC Check: in Section 1A".
