Here's what I would do,,,,, Disconnect both of the sm. terminals wires. With the key ON you should see 12v in one of them. Put that one back on the relay and just use a jumper to Ground the other sm. post that still has the wire off it.
Does the relay "throw"? If so, there is a problem with the PCM being able to supply Ground to the relay (PCM itself / wiring / bad sensor making the PCM think the engine doesn't need the GPs)
Does the relay NOT "throw"? If not, the relay is just Bad....
