DISCHARGE FUEL SYSTEM PRESSURE
Check that the battery voltage is above 12 V.
Disconnect the negative terminal cable from the battery.
Disconnect the fuel hose from the fuel filter assembly.
Install SST (pressure gauge) using SSTs and a fuel tube connector as shown in the illustration.
Wipe off any splattered gasoline.
Reconnect the negative terminal cable to the battery.
Connect the intelligent tester to the DLC3 (See step 1 in check fuel pump operation).
Measure the fuel pressure.
| Fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses, fuel hose connection, fuel pump, fuel filter and fuel pressure regulator.
Disconnect the intelligent tester from the DLC3.
Stop the engine.
Measure the fuel pressure at idle.
| Fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If pressure is not as specified, check the vacuum sensing hose and fuel pressure regulator.
Stop the engine.
Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.
| Fuel pressure |
|---|
| 147 kPa (1.5 kgf/cm2, 21 psi) or higher |
If pressure is not as specified, check the fuel pump, pressure regulator and/or injector.
After checking fuel pressure, disconnect the negative terminal cable from the battery and carefully remove the SST to prevent gasoline from splashing.
Connect the fuel hose to the fuel filter assembly.
Reconnect the negative terminal cable to the battery.
Check for fuel leakage.
