I bought a 2004 BMW 545i for a very attractive price. No Crank No start with a broken keyfob. 1st thing I do is buy a new battery & attempt to start the car. Everything turns on Dash works in “on” position, when the key is turned to “Start” .... No sound not even a click from the starter relay. Due to my past experience with BMW’s & EWS problems I bite the bullet , invest in a new key from a reputable locksmith. Same outcome only difference that I didn’t pay attention to at first was the fuel pump clicking in the “On” Position , I tested for fuel flow at the Schrader valve & it squirts out. Foot on the the brake , car in park ..... Turn the key to “Start” Position..... Nothing at all. I’ve done a lot of research & everywhere I look basically says if the starter is bad you will hear some type of click when turning the key. I have a multi-meter & ability/know how to test/ trouble shoot , where should I start? Does it sound like a bad starter or something else?
More BackGround: The previous owner took it to your regular backyard mechanic, who Knew nothing about BMW’s & tried horribly to troubleshoot the car (I have 2 alternate ECU/TCU) They claim the starter was changed. Also the plastic covers in the engine bay where left off so the inside carpet was soaked for a good month (not sure if any of this matters but just fyi)
