    2001 BMW 325i Won't start. HELP

    Hello, I have an 01 BMW 325i, it doesnt want to start or crank. Battery is good, I have the main key with a good battery in it as well. Does like a humming noise thats coming from the engine bay. Thinking it could be the fuel pump. Would really appreciate the help. Thanks in advance.

    When you say the battery is good, what voltage you are seeing?

    Fuel pump is located under the back seat.

    Good battery, no crank, good chance it's a starter.

    Try the other key. The car has a theft prevention system called the EWS. The EWS won’t send exciter voltage to the starter unless the key sends the correct code to the EWS. The starter has power at all times.

    If the second key has the same results take a piece of wood and a hammer and whack the starter.
