WARNING: This page is about a different car, the 1996 Ford Aspire. However, it is still accessible from the selected car via links, so may be relevant.
- Connect fuel pressure gauge between fuel filter and fuel rail. Open main valve and close drain valve. Locate fuel pump test connector in engine compartment behind battery, at left shock tower.
- Connect jumper wire between fuel pump test terminals. See Fig 1
. Turn ignition on. 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. Verify residual pressure is at least 21 psi (1.5 kg/cm2
).
- Operate fuel pump by reconnecting jumper wire at fuel pump test connector. Check fuel pump performance. Pinch hose between pressure gauge and fuel filter. DO NOT pinch hose longer than necessary to measure pressure. See FUEL PUMP PERFORMANCE
table. If pump does not meet specifications, inspect fuel pump circuit, fuel pump, fuel tank and fuel filter.
