2000 BMW X5 Questions

I checked the fuse, replaced the relay, checked the pump and everything checks ok, If I turn the ignition to on position the pump turns on for a couple seconds only, the pump will not stay on.

I have a 2000 bow x5 4.4i the rear air suspension is all the way down, I checked the fuse and its ok, I checked the pump by bypassing the wires and it's ok the pump works fine. When I turn the key to the on position, the pumps turn on, but only for a couple seconds then it turns off, I checked and replaced the relay and still does the same thing. The pump only turns on for one second, has someone had the same problem before?? Please help

Says it has a clean title but other than that there is no info on any issues.

Recently bought a new key for my car and now the new key nor the old doesn't work. I know it not my starter because I ran a Hotwire to it and it still crank but doesn't turn over. Kind of lost on what should I do any suggestions would be greatly appreciated

i tried using a 10mm socket, but it seems to big, and the 9mm is too small. am i missing something here?

The problem noted above happens constantly.

WHEN CRAKING IT JUST KEEP TURNING OVER AND OVER BUT NOT CRANKING AFTER SEVERAL TRYS IT FINALLY CRANKS. BUT SOME TIME I SMELL GAS WHEN I KEEP TRYING. wHAT COULD THIS BE?

a/c blows cold air from left dash vent but blows warmer as it goes to the passenger side.

I have lost my odometer reading and the screen where all the failure messages keep popping up. Also have a check engine light ABS & Brake msg. Yes my dash looks like a x-mas tree! But really need to get the odo back up. Is this an actual instrument cluster replacement or pixel repair
