Bad Bad X5

[Xman13]

01 E53 3.0 I am having problems with my X5. When its below 70 degrees it wont start. It will crank fine but never even pops. Once its warm it fires right up every time. then next day nothing.

I have recently replaced:
Camshaft sensor
Crankshaft sensor
Fuel pump

My thinking is a relay. I dont know which is the fuel pump relay. The one in the cargo area or the one on pass side firewall by the DME. But I have swapped them around.

I used a meter and wasnt getting power to the pump. Now that it has warmed up I do for about 3-5 seconds. Normal I believe. This is to prime the fuel line. The weird thing is that when I hook up the fuel pump I get no gas out of it during those 3-5 seconds? It never kicks on. There is no pressure at fuel rail. No gas at all.
