If you know what pins go where, and i think they usually have a little diagram on the side of them ??
Check for continuity on the energizer coil ... .check for power at the proper time to the energizer coil. If the relay is being energized, then make sure the signal or voltage level going in, is making it back out ... remember the relay is just like a toggle switch thats being flipped by the energizer coil instead of your finger. So you have two things to check ... the energizer coil (the thing that flips it on and off) and the switch itself (which is just some contacts that if closed let the signal pass and if open stop the signal at the switch).
This is one of those things where the concept is simple, but its difficult and complicated to explain
