Depends on exactly what you did.  The way it is supposed to behave is this:
the relay gets its power from the switched ignition feed, i.e when you turn 
the key to position 1.  It will operate the fuel pump for a couple of 
seconds, without the engine turning, before cutting-out.
After the first couple of seconds, it needs a regular signal from the 
ignition circuit to keep it going.
The end result is, if you turn the key straight round to position 2. then 
it's going to start cranking straight away.  If you turn to position 1 only, 
you should hear the pump going for a couple of seconds, then cutting-out.  
Ther should be no need for the pump to prime the circuit as system pressure 
should be maintained by the regulator, unless you've got a faulty regulator 
or leaky injectors.

Not true. If you open the throttle, there will be less restriction in the 
air flow therefore you will get greater airflow & greater fuel flow.  In my 
own case, I could turn the car all day, if it is cold, and it won't start 
without a prod on the gas.

Proves my point!
Every car is different - some need more help than others cold starting.
