Hi,im having an issue with the relay intermittently not working unless I tap it with a screwdriver handle once in a while. There are two relays on the firewall on the driver's side of the car. The one I have been tapping is the one off the the right. I noticed today that both of the relays are the same exact part number. The one to the left is for the fuel pump,correct? The local parts house wants $28 for this thing

 

What colors are the wires?

No big surprise that they're the same part #... a relay is a pretty dumb thing basically, just an electromagnetically operated switch. Kinda like, in your house, there's no reason that the switch for the kitchen lights and the one for the disposal, have to be different. They do the exact same thing, electrically.
