Fuel Pressure: Testing and Inspection
NOTE: Check for a clogged fuel filter and/or fuel line before checking fuel pump pressure.
1. Remove the fuel cut-off relay from the fuse box.
2. Connect the 1st terminal to the 2nd terminal located at the fuse box side of the fuel cut-off relay.
WARNING: Do not smoke during the test. Keep any open flame away from your work area.
3. Disconnect the fuel line at the fuel filter in the engine compartment, and connect a pressure gauge to it as shown.
4. Turn ignition ON until pressure stabilizes, then turn key OFF. Pressure should be 17.7-22.6 kPa (2.6-3.3 psi).
a. If gauge shows at least 17.7 kPa (2.6 psi) go on to step 4.
b. If gauge shows less than 17.7 kPa (2.6 psi), replace pump and re-test.
5. Remove pressure gauge and hold a graduated container under the hose.
6. Turn ignition ON for 60 seconds, then turn ignition OFF and measure amount of fuel flow. Fuel flow should be more than 760 cc (25.7 oz.) in 60
seconds.
a. If fuel flow is 760 cc (25.7 oz.), or more in 60 seconds, reconnect cut-off relay and fuel hose.
b. If fuel flow is less than 760 cc (25.7 oz.), replace the fuel pump and re-test.
NOTE: Check for a clogged fuel filter and/or fuel line before replacing pump.
