Just leave the ignition on for maybe 5 minutes.
Allow the fuel to get pumped back to the engine.
I'm assuming it's an auto.
Hold the throttle to the floor for about 20 seconds & then try turn it over. (Don't forget to take the foot off if it starts up!)
There's a good chance your fuel filter is clogged up with any dirt/debris that might have been in the end of your fuel tank.
I would suggest replacing the fuel filter in the mean-time even if it does start.
Fuel pumps are known to break if the fuel line runs dry, a bit like some water pumps I suppose. You should be able to hear this when the ignition is at position II (just before starting). If it's running this obviously isn't the problem.
Check the fuses if you can't hear the pump. (You never know).
Let me know how you get on!

So I know that it doesn't make much sense and it should start after putting the gas in. But... As sealed as the gas tank is, there is dirt and sediment that gets into it anyway and settles at the bottom of the tank. If run out of gas, sometimes that dirt and debris will get pumped through and will clog up the fuel filter and once in a great while, will ruin the fuel pump. Best bet though before you start replacing that stuff is continue to try and start it. Don't crank and crank the engine but try starting it a couple times and that will get fuel back into the system and hopefully it will start for you. Hope it helps!

Instrument cluster dead after Battery replaced


It is possible AAA worker connected the battery backwards for just a second and got a big spark. This can cause major issues, but sometimes just minor ones, such as blown fuses. Check every fuse for starters. There are also fusible links in the wiring which can be blown.

'97 540i spluttering & cutting out


best bet is to go get any codes that may be stored in the PCM. This will take alot of the guess work out of diagnosing it. Or remove the spark plgs and replace them.. If you have 50,000 or more this could be the cause but a code may tell you which one is the issue
