Checking fuel and residual pressures
Note! For vehicles with demand activated fuel pumps (FP), see VIDA vehicle communication Quick test of fuel pump (FP).
Measuring the line pressure
Connect the pressure gauge according to Fuel pressure gauge See: Fuel Pressure Gauge
Remove the soundproofing panel
Remove the fuel pump (FP) relay (CMI 12 in the passenger compartment)
Connect a cable to the relay base as illustrated.
Read off the line pressure from the pressure gauge. The line pressure must be 375-395 kPa.
Check the residual pressure if the fuel pressure is OK.
