WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools Required

Fuel pressure gauge 07406-004000B
Fuel pressure gauge attachment set 07AAJ-S6MA150

Relieve the fuel pressure (see FUEL PRESSURE RELIEVING )
Attach the fuel pressure gauge set and the fuel pressure gauge

Start the engine, and let it idle
- If the engine starts, go to step 5
- If the engine does not start, go to step 4
Check to see if the fuel pump is running Listen to the fuel filler port with the fuel fill cap removed The fuel pump should run for 2 seconds when the ignition switch is first turned on (II) or engine start/stop button to select the ON mode
- If the pump runs, go to step 5
- '09 model without SH-AWD, '10 - 11 model: If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING )
- '09 model with SH-AWD, If the pump does not run, refer to the DTC TROUBLESHOOTING
Read the fuel pressure gauge
Fuel pressure should be.

392-441 kPa (4.0-4.5 kgf/cm ² , 57-64 psi)
- If the pressure is OK, the test is complete
- If the pressure is out of specification, replace the fuel pressure regulator, without SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ), with SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter, without SH-AWD system (see FUEL FILTER REPLACEMENT ), with SH-AWD system (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure
