Fuel Pressure Check
- Connect fuel pressure gauge between fuel filter and fuel rail. Open main valve, and close drain valve. Locate fuel pump check connector in engine compartment, near left strut. Connect jumper wire between fuel pump test terminals (Black and Green/White wires on Capri; Black and Green/Red wires on Festiva).
- Turn ignition on to activate fuel pump. If pump does not run, check fuel pump circuit. If possible, start engine. Measure and record fuel pressure. For fuel pressure specifications, see FUEL PRESSURE SPECIFICATIONS article. Disconnect vacuum from pressure regulator. Turn engine off. Wait 5 minutes, and verify residual pressure is at least 21 psi (1.5 kg/cm2 ).
- Operate fuel pump by reconnecting jumper wire at fuel pump check 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 table. If pump does not meet specifications, check fuel pump circuit, fuel pump, fuel tank, and fuel filter.
