Fuel Pump Test
- Check for clogged fuel filter and/or fuel line before checking fuel pump pressure. Remove fuel cut-off relay from fuse box. Connect No. 1 terminal to No. 2 terminal located at fuse box side of fuel cut-off relay.
- Disconnect fuel line at fuel filter in engine compartment and connect pressure gauge. Turn engine on until pressure stabilizes, then turn key off. Pressure should be 2.6-3.3 psi (0.18-0.23 kg/cm2 ). If gauge shows at least 2.6 psi (0.18 kg/cm2 ), go to step 3. If gauge shows less than 2.6 psi (0.18 kg/cm2 ), replace pump and retest.
- Remove pressure gauge and hold a graduated container under hose. Turn ignition on for 60 seconds, then off and measure amount of fuel flow. Fuel flow should be more than 25.7 oz. (760 cc). If fuel flow is 25.7 oz. (760 cc) or more in 60 seconds, reconnect cut-off relay and fuel hose. If fuel flow is less than 25.7 oz. (760 cc), replace fuel pump and retest.
NOTE:
Check for clogged fuel filter and/or fuel line before replacing pump.
