BMW 535i wont start

I have a 1990 BMW 535i that one day just would not start up. I had no problems before hand, just turn the key one time and it started. Now the engine cranks over but will not start. Check the fuel pump and it is not cutting on, so I checked the fuse and there is no fire to the fuse that goes to th fuel pump. Is there anything else I should check before the fuse? Before I pay $200- $300 for a pump.:banghead:

See if the ECU is sending out a signal for the fuel pump?

i had the same thing happen once, it was because i disconnected the battery and when i reconnected it the security feature on my 89 535 thought i was steeling it. so i would check that
