Fuel Pressure

SYSTEM PRESSURE
^ Must be: 4.0-4.2 bar (58-61 psi) with fuel pump running
^ Must be: 3.4-3.7 bar (49-54 psi) immediately after fuel pump (remote control) is switched OFF

Vacuum Applied To The Fuel Pressure Regulator
Observe pressure drop on fuel pressure gauge.
^ Must be approximately 0.5 bar (7 psi).

RESIDUAL FUEL PRESSURE
- Wait 10 minutes
- Check residual pressure.

Minimum acceptable pressure values:
- Cold engine: 2.5 bar (36 psi)
- Warm engine: 2.8 bar (41 psi)
