    E36 318is - Fuel pump issue?

    Brought it for a spin there tried it on the hills out our own road will pull up the hills in first no problem no throttle. Spirited spin then no problems al all. Must have just been dirty petrol or maybe something is about to die. Pump doesn't sound weak or weird either sounds normal enough.

    E36 318is - Fuel pump issue?

    So I swapped the fuel pump rely for a spare I had. I also checked the filler cap and the rubber seemed a bit dry not perished though. Seems to be loosing its shape. I put some silicone lubricant on it. Would this seal be enough to cause my symptoms?

    I just cleaned the Idle Control Valve and it sorted it.
    Depressing and all as it is this is still happening. Car started normally drove 1 mile car stalled at a junction and would start run for 10 secs and them die.

    What does the idle control valve look like in M44 is it the black circle round thing?

    How do I know if it's the cam sensor that is faulty?

    Idle control valve wouldn't cause an issue like this

    You need to get a diagnosis done its the only way forward

    E36 318is - Fuel pump issue?

    Ya a few people have suggested it but afaik mine is new I changed it myself. It's a black circle about 1cm high with two bolts that come out with an Allen key.

    Just reading some old posts and they seem to be suggesting cam sensor?

    From past posts cam sensor is sounding like a likely culprit

    Im not sure if a sensor like that can be diagnosed without using the computer

    Keep us posted on what the diagnostic reveals tomorrow
