Hva betyr feilkoden?

The CEM registers that the signal from the fuel pump is missing, and the fault is permanent. The engine then does not start, and the starter motor may crank the engine without it firing.

Mulige årsaker

No signal from the fuel pump

Hva du kan gjøre

1Check the fuel pump fuse. If it has blown, replace it once. If it blows again, use a multimeter to check the wire after it has no contact with ground
2Check that the connectors to the CEM and to the engine control module are seated and not corroded or chafed
3With a diagnostic tool, activate the fuel pump and listen for it to start
4After the work, clear the code and check that the engine starts
