You replace the fuel pump relay, but did you check to see if the fuel pump is working?

You can remove the gas cap, have some one turn the key to the start position and listen for the hum of the fuel pump spinning. The fuel pump will only spin for a couple of seconds and if the engine doesn't start it will shut down.

How much gas is in the tank? If it reads less than half you could have a bad transfer pump and the side that the pump is located in could be empty.

Added some gas to it and start it up after a few tries..Thanks alot what does this mean the level unit is bad? or should I just try to have more then half a tank at all times.? ..Again thank you very much :thum bup:

Unless you replace the transfer pump, you must keep the tank above half empty in order not to have this problem. Running the fuel pump when there is no gas on that side of the tank will eventually wear out the fuel pump.

Am I have a recurring dream? I swear you just answered this same issue last month and got back the same answer...It started!

My friend has a 2001 X5 with the 3.0 for parts do you know if they're interchangeable?

You can go to Realoem.com and check to see if the part numbers for the 3.0 and 4.4 are the same.

good call on the fire extinguisher! (almost had visions of disaster when you suggested to touch the plug to the threads, and youll see a spark ! sure you will!
sound advice, the fuel pump is located under the back seat (passenger side, it will make a whiring sound as others have said, i have found it useful to cycle it a few times (on 5 sec, off then on 5 sec and try start) just to make certain the fuel is at the injectors, if you were out of fuel, you may not know it if the sending unit is toast (dont ask how i know that!! add a couple liters of fuel and see if that makes a difference!
best of luck.
