Hello, it was suppose to be a simple task today, replace the 3 year old fuel filter in my 740 GLE wgn. Well, it's in but now the car will not start. It did after a few turns for a couple minutes than it just died. I don't get the "buzzing" sound when I turn the key to the first position, like I did before? I was going to do the in-tank prepump next, but now I'm a little worried. I think I wired it back correctly, black on top and red wire plugged into bottom??? Any help/suggestions will be greatly appreciated. Thanks!
