What it means

The fuel pump delivers fuel from the tank to the engine. The computer found a fault in the pump supply or control. The computer sees no current in the circuit, so something is open: a wire, a connector or the part's winding.

What you may notice

No start or hard starting
The engine cuts out while driving
Less power

What could be wrong

1Connector loose, damp or corroded · Wiring or connector repair €45–90
2Wire broken or chafed · Wiring or connector repair €45–90
3Faulty fuel pump · Fuel pump replacement €250–500
4Engine computer fault (rare) · Control unit check and software €150–300

Repair difficulty: Moderate

What you can check yourself

First look at the connector and wiring: anything loose, melted or green with corrosion? Switch the ignition on and listen for the pump humming from the tank for a couple of seconds. Check the fuse. Best left to a workshop. It needs a diagnostic tool and experience.
