X5 only startsif i jumpfuel pump relay

SOURCE: no power to fuel pump

What you need to do is drop the fuel tank and put a new fuel pump in it. I would drain the gas and put new gas in after you get the pump changed.

SOURCE: fuel pump will not run

THERE IS A FUEL PUMP SHUT OFF SWITCH(INERTIA) ON THE PASSENGER SIDE KICK PANEL.INSIDE CAB UNDER DASH.IT INTERUPTS POWER TO THE PUMP IF U ARE IN A COLLISION.PUSH THE RED BUTTON ON TOP OF IT.IF THAT DOES NOT WORK CHECK FOR POWER IN AND POWER OUT.NO POWER OUT BAD SWITCH.NO POWER IN OTHER PROBLEM

I've been bitten by this twice! The culprit both times was the connector plug under the van infront of the fuel tank. the second time the connector pin and socket came loose inside the plug itself,( workes for a while then dosen't). Make sure there is good secure contact made in all sockets in this plug, and the pins are held where they need to be inside the plug itself.

first alway check the simple things first like fuses and relays then start playin with changin out parts. under the hood you sould find a fuse panel if the lid does not tell you what is what you need to look into the service manuel find the fuel pump relay and switch it with the same type relay can works some the doesn't effect the engine like a fan relay for expamle. then try to start engine when turning key to the run pos you sould hear a fant hum or whine from the pump. if thats a no go take the main fuel line off before the fuel filter and see if a good stream of fuel comes out when you turn key to run pos.if so replace fuel filter.
