Hello,
My friend was driving back from vegas as I was asleep. I woke up to us running out of gas. Triple A came and added more gas. Enough to put the needle over the second line but NOT half a tank.
When I try to start the car it will not start. The battery is fine and it sounds like its really trying to start but that there is no fuel in the engine.
What I have tried:
- Turning the key to positon 2 frequently.
- Checking the fuel pump fuse (Not blown)
- Starting the car while pressing on the gas.
When I turn the key to position 2 and put my ear to the back seat where the fuel pump is I do not hear any noise. Should I always hear something when the key is put to position 2?
Any insight is appreciated. Thanks!
EDIT: I have one more question when you put the key to position 2 should you ALWAYS hear the fuel pump turn on or is this just what happens sometimes when your car has run low on fuel?
Update: Bought a new fuel pump (BOSCH) and have been watching various videos and saw that the hose clamp may need to be replaced if its factory. Does anyone know what size the clamp is so I can have it purchased just in case. Thanks!
Update: It was indeed the fuel pump. I followed a DIY on here and replaced it. The car is running smoothly now! Many thanks to everyone that helped! I am extremely grateful! The mechanic asked for $600!

Hearing its fuel pump what do you think of this? : http://www.ebay.com/itm/Gas-Fuel-Pum...1ZH6xs&vxp=mtr

The problem with the intank fuel pumps that BMW uses, the fuel has to keep it cool. So if you regularly run under 1/4 tank, you risk overheating the fuel pump depending on where you live. As I notice CA, the more south, the greater the risk for failure. There is a good chance that the fuel pump is burned out, but you will need to test it first. There should be 12V while cranking at the fuel pump, and at the same time, you should hear the pump engaging.

Keep priming and cranking. After I changed the fuel filter on my E46 it took an inordinate amount of time spent priming and cranking to get it refired. Air in the lines I guess.

Remove the rear seat. Remove the four screws for the Fuel Pump cover on the passenger side. Turn the key to ON position 2. If you cannot hear the fuel pump whirring and lightly tapping on it has no effect, replace the Fuel Pump.

Yes.

Bang on the right side of the gas tank while someone cranks the car. If it starts the fuel pump failed. This can be done from above if you are by yourself. Remove the rear seat bottom and the fuel pump access panel and tap the top of the fuel pump being careful not to hit the fuel line (plastic nipple can break)

Only momentarily unless cranking or running

I should have been a little more clear. You are correct and in a sense, so was I. You turn the key to position 2, you should hear the fuel pump whirring but it won't stay whirring unless you continue on to starting the car.

The factory clamp cannot be reused - and I used a pair of wire cutters to cut it off. I then used an 18mm from a variety pack of 12 I got at the Dollar Tree.

Fancy seeing you here! Again thanks bro.
