In my 1992 3.0 the Fuel Relay is going nuts, even after I replaced it. I tightened the ground strap bolt coming off of the negative terminal and cleaned the post and the clamp because I heard this was a ground issue. Any other ideas?
The engine also seems to be stumbling when started though it smooths out after it gets warm.

Any help will be greatly appreciated; this is my only car and my wife and I need it to get to work.

EDIT: The relay is in my power distribution box, and is labeled E5SB 11433 A2A. It's a black relay with a green/orange wire, a red wire, a red/orange wire and a black/yellow wire coming out from the connector.

Edit 2: I just used a code reader and I'm getting Codes 565 and 629. Maybe this isn't the fuel relay? I think I read somewhere that the fuel relay is green.
