I've got a 2000 BMW 328i crank no start and no codes. The relay and fuse is fine from fuel pump but there's no power going into the fuel pump. I've checked the inertia switch. Could it be a bad camshaft sensor since they have both just been changed?

With a no start, "codes" don't really figure in If your fuel pump isn't getting power, not knowing anything about your vehicle, is it possible that there's an anti-theft concern here? What are you doing to test for power to the fuel pump? Do you have a wiring diagram and a voltmeter? I honestly didn't know there was an inertia switch on this vehicle. I suppose referring you to a local BMW shop and tech near you is the best idea. www.repairpal.com/repair-shops
