Measuring the line pressure
- Connect the pressure gauge according to Connecting 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.
Remedy as necessary.
