Question on the fuel pump relay.

This is a continuation of a long, long thread but let me just ask a direct
question... I had my fuel pump relay break on me today and I do not think
its working anymore. I have jumpered the 2 big terminals and put that jumper
wire on a switch so that I can turn the fuel pump on and off with a switch
as needed. This is only a temporary fix till I get some other bugs worked
Question: Does the relay send variable voltage to the pump? Meaning, does it
sometimes open it up full bore (12V) and sometimes run it at a slower speed
(less than 12V) depending on engine demands?
If someone could answer that direct question that would be great.
Again the car is an 85 4000SQ (5Cyl, CIS-E)
