Does it cranks, If it is try checking your fuel pump. It sounds like it starve. You might have to replace the F-Pump. I have the same problem with my 3 series bmw 2000. Your issue may just be similar.

I would also check the fuel filter. It could be dirty and clogged. It's alot cheaper than replacing the fuel pump first.

Yes, a clogged fuel filter will be something to check. But if you listened to the fuel pump and you don't hear the hissing sound of the solenoid, more likely it Is the pump. It's cheap if you get it from amazon. I replaced mine two years ago and still running.
