Fuel Pressure: Testing and Inspection
Fuel Pump Testing
1. Connect a jumper wire between the two black/yellow wires at the fuel pump cutoff relay connector.
WARNING: Do not smoke during the test. Keep any open flame away from your work area.
2. Disconnect the fuel line at the fuel filter in the engine compartment, and connect a pressure gauge to it as shown.
3. Turn ignition ON until pressure stabilizes, then turn key OFF. Pressure should be 0.15-0.20 kg/cm2 (2-3 psi).
a. If gauge shows at least 0.15 kg/cm2 (2 psi) go on to step 4.
b. If gauge shows less than 0.15 kg/cm2 (2 psi), replace pump and re-test.
NOTE: Check for a clogged fuel filter and/or fuel line before replacing pump.
