Re: Fuel pump question

It should have both but the relay is between the brake booster and the fender on the firewall grey oval shaped. Fuse is in the fuse block.

Re: Fuel pump question

I see 3 relays between the master cylinder/ firewall and one mounted on the passenger fender next to the battery. Which one powers the fuel pump?

Re: Fuel pump question

On my car and I think yours as well the two identical ones are the fan and fuel pump relays. Fan relay has four wires going to it, the fuel pump
relay has five. If you have two fans the other one may be the relay for the other fan also with four leads to it
