1995 1.3 Festiva not starting

[5.8]

I have a 1995 1.3 Festiva for a work car. It has just over 130,000km on it. I went to start it the other night and after initially nearly starting it will now just wind over as per usual but no go. I pulled the fuel lines and checked the filter, all good. When I take the air intake off and put a bit of fuel into the chamber it starts and runs until it uses the fuel and then cuts out. Believing it was the fuel pump I then fitted a new Goss pump to it and it still has the same problem. It happened about 5000km ago and after putting fuel in via the air intake it started and has run fine up until now. Any ideas fellas?
