Check power cables, power fuse and ground connection. The pump need 80A when full load and if poor connection the voltage drops,pump loose communication and stop.

The oil problem inside the pump is not in this car is in peugeot 307, in this case check for the connector that is go in to the pump a lot of problem with it and check the MF fuse for worn legs from heating.
