Hi to everybody.
Could anybody help me please with my problem? My car is BMW 525TDS (April, 1993 year ). I know when I put the key on ignition ( not starting the engine, just switch on the key ) the electric fuel pump ( which is in fuel tank ) should work ( a short time ) to supply the fuel to engine ( before starting the engine ). It doesn't work. What could be the reason? I have checked the voltage on fuse N23 ( the pump's fuse. The fuse was OK ) and there was not a voltage when I switched on the key on ignition state. The relay which supplies the voltage to that fuse also was OK. I think that from a reason (I would like to know WHAT reason ) the DDE doesn't send signal to mentioned relay. Maybe by the some reason there is insufficient pressure in fuel supply system? :(
My thanks to everybody who will reply to my issue.
