240 Turbo main pump is super noisy and loud. When i turn the key (but don't turn it all the way to start the engine) the fuel pump comes on for a few secs and then should turn off, right? At least that's how my friends turbo is. He'll turn the key to the accessories setting and you'll hear his main fuel pump kick on for a few seconds and then go silent. That is, of course, until you start the car, and then you hear it whirring all the time. My fuel pump kicks in when i turn my key to accessories too, but it won't shut off - and it's really really loud too. I'm also having driveability issues with sputtering and stuff and i have really bad cold start issues. Sounds like a main pump problem in my view. Any ideas or thoughts otherwise?
