hi, i have a 330 diesel on a 03 plate. when the car has been felt for a while it seems to not want to start it cranks for about 10 seconds till it starts. the car has had a new fuel pump, filter pump relay. i used a scanner on it and the code 09f6 fuel rail pressure sensor came up, i replaced the sensor and the one way valve, and the fuel flow sensor still it takes a long time to start, when i put my boost charger on it seems to fire first time ?? does any one have any ideas??

cheers

poor battery?

tonytech

no battery is brand new
just seems like the booster is maybe giving the fuel pump more amps or something??
