Yellow Relay Revisited.

I have been trying to figure out for the past several months why my fuel pumps come on with the ignition on and engine not running. It doesn't do it all the time. Finally wiggled the yellow relay with the ignition on and engine not running, turns out this is the problem. When I wiggle the relay the pumps come on. I know this has been discussed in length in several threads here, but does this relay have any other function than killing the pumps in a crash and over boost protection? I think I have read that it has several functions. Just wondering if this loose relay could be causing other problems? Car seems to run fine.
