Please help: I just bought a used Qubo 1,3 multijet diesel(2013) two month ago. It had several problems with fuelinjection leak and diesel smell. The dealer repaired the problems but now the fuelpump has problems sucking up the diesel.

It runs fine for 400 km and then after a short coffebreak it will not start.

You can hear the pump sucking bubles of air under the rear seats when turning the ignition on without starting.
Sometimes you can hear it humming the way it should and then you can drive 30 meters and then runs out of fuel. Then the bubble noise from the pump will continue for several minutes.

There´s plenty of fuel in the tank.

Any ideas ?
