FUEL INJECTION CONTROL SYSTEM INSPECTION
EF & EC-354prose procedureGA16DE engine (header tab).
Fuel Pressure Check (Cont'd)
- 5Read the indication of fuel pressure gauge.At idling:When fuel pressure regulator valve vacuum hose is connected. Approximately 245 kPa (2.45 bar, 2.5 kg/cm², 36 psi)When fuel pressure regulator valve vacuum hose is disconnected. Approximately 294 kPa (2.94 bar, 3.0 kg/cm², 43 psi)
SEF718K - 6Stop engine and disconnect fuel pressure regulator vacuum hose from intake manifold.
- 7Plug intake manifold with a rubber cap.
- 8Connect variable vacuum source to fuel pressure regulator.
- 9Start engine and read indication of fuel pressure gauge as vacuum is changed.Fuel pressure should decrease as vacuum increases. If results are unsatisfactory, replace fuel pressure regulator.
