PRESSURE GAUGE SETUP
1. Pressure gauge to fuel hose adapter
2. Fuel hose adapter to fuel rail
3. Fuel hose adapter to fuel pump pressure hose
10. Reinstall the fuel pump relay fuse (F15) in the
forward fuse box.
11. Turn ignition key ON and observe fuel pres-
sure.
FUEL PRESSURE
NOTE: Valid at 12v ± 0.1v.
12. Start engine and observe fuel pressure.
13. Stop engine.
14. Remove test equipment and reconnect fuel
hose to injector fuel rail by proceeding in the
same manner as for its installation.
Test Conclusion
The fuel pressure should be within specification in
static or dynamic tests.
Rapid Pressure Drop
If there is a rapid pressure drop after the engine is
stopped, check for leakage at:
– A fuel hose
– A fuel rail.
NOTE: The fuel pump check valve integral to the
fuel pump module may also be at fault.
If no leak is detected, replace fuel pump.
Slow Pressure Drop
If there is a slow pressure drop after the engine
is stopped, check for a fuel injector leak. Refer to
ELECTRONIC FUEL INJECTION (EFI)
NOTE: The fuel pressure regulator or fuel pump
check valve integral to the fuel pump module may
also be at fault.
If no leak is detected, replace fuel pump.
