1. Fuel Pressure - Relieve
2. Fuel Pressure - Test
NOTE: If you were referred to this procedure from a troubleshooting
procedure, test the fuel
pressure under the same conditions the malfunction occurred (engine speed, load,
throttle
position, etc.).
- Disconnect the quick-connect fitting and attach the fuel pressure gauge
set. Check for leaks
with the gauge set attached
- Start the engine, and let it idle.
- If the engine starts, go to step 3 and read the fuel pressure gauge.
- If the pump does not run, do the fuel pump circuit troubleshooting.
- Read the fuel pressure gauge. The pressure should be: 390-440 kPa
(3.98-4.49 kgf/cm2,
56.6-63.8 psi)
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure
regulator - Refer to: Fuel
Tank Unit Disassembly and Reassembly (2WD), or Fuel Tank Unit
Disassembly and
Reassembly (AWD) and the fuel filter - Refer to: Fuel Tank Unit

Test
1. Low Fuel Indicator - Test
- Do the gauge self-diagnostic test.
- If the low fuel indicator flashes, go to step 2.
- If the low fuel indicator does not flash, replace the gauge control
module.
- Check for body electrical system DTCs.
- If any DTCs are indicated, do the indicated DTC's troubleshooting.
- If no DTCs are indicated, go to step 3.
- Do the fuel gauge sending unit test and the secondary fuel gauge sending
unit test.
- 2WD: Test the fuel gauge sending unit - Refer to: Fuel Gauge Sending
Unit Test (2WD), or
Fuel Gauge Sending Unit Test (AWD)
- AWD: Test the fuel gauge sending unit - Refer to: Fuel Gauge Sending
Unit Test (2WD), or
Fuel Gauge Sending Unit Test (AWD) and the secondary fuel gauge sending
unit
