people make diagnosing a fuel pump harder than it is. Put a test light to the connector on the fuel pump. Have someone turn the key. If the test light goes on you are getting power to the pump and all the relays are fine. If the light goes on and you don't hear the pump prime its a bad fuel pump. If it doesn't light you aren't getting power to the pump. I just used standard hose clamps not the BMW crimp clamp. Just don't tighten it to much u risk breaking the plastic on the fuel pump that the fuel line goes on.
