Maybe this will help.
Also search for "fuel pump relay" and you will find ways to check it easily. Hopefully that is the problem because a relay costs $15-$20 at the dealer
I had the relay go bad on my E36 and confirmed that I had spark by squirting a small amount of starter fluid in my airbox. When it fired and ran for a second or two, I knew that I had a fuel delivery problem. Once you confirm that, checking the fuel pump and relay aren't that hard.
