The EFI relay is under the hood with the other relays. But I was wondering how to test it so I don't drop my tank for nothing.
I am going to assume that the 97 fuel pump relay is locate in the same place as the 99. It is inside the truck and as I said before it is behind the lower dash close to the hood and fuel door releases. It is black and about the size of a box of matches maybe a little smaller. You can put your finger on it and feel it when it is energized.
