2007 Clubman s manual with 70K.

Driving at freeway speeds when engine shuts down (like you turned off the key). Roll to the side and after a minute it started back up and ran for a week. Next time not so lucky, again 70mph and just stops running. No idiot lights or failure codes stored. Towed to a BMW / Mini mechanic on a Saturday and on Monday am it started right up.
The HPFP was replaced one year ago via the Mini recall. Next guess was to replace the primary fuel pump. It ran like a champ for 100 miles and then back to the side of the freeway. Towed it again and now discovered voltage to primary fuel pump is 0 volts DC.

Any ideas on how voltage to the primary fuel pump could be so erratic? I would think it is either there are fails altogether.

Thanks

need to check wiring back from fuel pump might be a faulty ecu signal wire or ecu its self at worst, one of these faults a good tech will find easy maybe,

Check fuse on the JBE to make sure the fuel pump relay is getting voltage. If not, the fuse panel, the JBE, needs to be replaced and re-programmed.
