Default HELP!! My Audi 100 won't start!

Hey all,

I need some help here. Let me give some background on my problem, a few weeks ago I stupidly ran out of petrol on my way home, got her refueled and on her way but a week later she started back firing and loosing power intermittently. I parked her up and had a look and I can't get her going since. Here's what I did. I originally thought it was the HT leads, I did find one that was damaged so I changed the leads, plugs and the coil just to be on the safe side. She fired up again and I drove it around the block to see if she was ok and it cut out and wouldn't fire again. It had a full tank of fuel but it cut out like it had ran out of petrol. I got her back to the garage and since then I've replaced the petrol filter, bled the system for air leaks, checked the cold start valve, checked for air leaks, fuel leaks and checked the metering head. It's been trying to start, I've been bleeding the fuel at the metering head which seems to help but she never stays going for more than 10-20 seconds. My pump seems ok, I'm not hearing any humming so it seems operational, although I must admit I can't hear it at all which makes me wonder? One other thing that seems to have help get her fired up is leaving the ignition on for a time, like it's building up fuel, she'll fire up when this is done but will die shortly after. Any ideas guys, I'm scratching my head here?
