Fuel Pressure
- Disconnect circuit opening relay (located behind left kick panel). Start engine (if possible) and allow to die. Connect pressure gauge to fuel line at fuel filter.
- Turn ignition on. Using a jumper wire, connect terminals (Black and Green/Red on Festiva or Yellow fuel pump check connector on Tracer) together. Fuel pump check connector is located on firewall, near windshield wiper motor. If pump runs, check fuel pump circuit.
- If possible, start engine. Check fuel pressure with vacuum connected to and disconnected from pressure regulator. Turn engine off and disconnect jumper wire at fuel pump check connector. Wait 10 minutes and ensure residual pressure is at least 21 psi (1.5 kg/cm2 ).
- Operate fuel pump by jumpering fuel pump test connector. Check fuel pump performance. Pinch hose between pressure gauge and fuel filter. Do not hold longer than necessary to check pressure. See FUEL PUMP PERFORMANCE (FUEL INJECTION) . If pump does not meet specifications, check fuel pump circuits, fuel pump, fuel tank, fuel filter or replace fuel pump.
