Re: HFS-3 on BMW 535d
Installed everything like said in the manual. Tested the system, pump and everything works, but when start the engine nothing happens.
Tried with injector +/- and now I linked MPS in the ecu(it should activate then manifold pressure detecion? And i connected the blue wire in the grey harness to MAP sensor. Nothing happens, doing this i disconnected injector wires.
I will post the picture of my ecu later.
