Fuel Pressure Control Valve (Turbo Models)
- Mark fuel pressure control valve vacuum hoses for installation reference. Disconnect fuel pressure control valve Blue striped and Black vacuum hoses. Disconnect fuel pressure control valve electrical connector.
- Connect battery voltage to fuel pressure control valve terminals. Using a hand held vacuum pump, apply vacuum to fitting from which Black vacuum hose was connected.
- When battery voltage is applied, vacuum should hold. When battery voltage is disconnected, vacuum should not hold.
- Disconnect battery voltage. Using an ohmmeter, check resistance between fuel pressure control valve terminals. Resistance should be approximately 36-46 ohms at 68°F (20°C).
- Replace fuel pressure control valve if it does not test as described.
