Check for pressure in the fuel tube sub-assembly from the fuel line. Check that sounds of fuel flowing from the fuel tank assembly can be heard. If no sounds can be heard, check the relay, fuel pump, ECM and wiring connectors.

Inspect for fuel leaks.

Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

Turn the engine switch off.

Disconnect the GTS from the DLC3.

Measure the fuel pressure.

Standard Fuel Pressure:: 196 to 833 kPa (2.0 to 8.5 kgf/cm², 28 to 121 psi)

If the fuel pressure is more than the standard, replace the fuel main valve assembly.

If the fuel pressure is less than the standard, check the fuel hoses and their connections, fuel pump with filter assembly, fuel filter (fuel suction plate sub-assembly) and fuel main valve assembly.

Disconnect the GTS from the DLC3.

Start the engine.

Measure the fuel pressure at idle.

Standard Fuel Pressure:: 196 to 833 kPa (2.0 to 8.5 kgf/cm², 28 to 121 psi)

HINT:: Refer to Standard Idle Speed.; Click hereEngine / Hybrid System>7GR-FKS (ENGINE MECHANICAL)>ENGINE>ON-VEHICLE INSPECTION201902,999999,_51,_078603,_0381337,RM100000001FZOT_01_0011,

Stop the engine.

Check that the fuel pressure remains as specified for 5 minutes.

Standard Fuel Pressure:: 98 kPa (1.0 kgf/cm², 14.2 psi) or more

If the result is not as specified, check the fuel pump with filter assembly, fuel main valve assembly and/or fuel injector assemblies.

After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent fuel from spraying.

Check the high pressure side fuel pressure at idle (shift lever in N, engine warmed up and A/C off).

Standard Fuel Pressure:: 1800 to 2800 kPa (18.4 to 28.6 kgf/cm², 261 to 406 psi)

If the result is not as specified, check the fuel pump, fuel pump assembly, fuel pressure sensor and wire harnesses.

Stop the engine.
