Before you replace the GP, find out if the ones you have are getting energized. Does the GP relay click when the key is turned to the run position? If it does check whether there is 12 volts at the GP.

Also, take the 8 hole connector out of the GP relay and check the resistance of each GP in the connector holes to ground. Each GP should read .04 to .08 ohms.

R&R the other connector on the GP relay about 10 times. Sometimes corrosion makes an open circuit between the connector and the GP relay and R&R should work thru it.
