In the fuse box on a my car, which relay is the fuel pump relay? I do not have a layout of the fuses and relays. Thanks

My car has a v6 manual. I am having some trouble with it running rough after I stop. I will be going at a good rate of speed and then come to a quick stop, and the car bogs down like it is going to shut off. During acceleration there is major hesitation, only sometimes though. I am just wondering if it is the fuel pump relay or if it is the fuel pump itself?

I would say fuel pump would cause other symptoms at all speeds and times. So it is not likely suspect. You can run pressure test to check it. Some people hook up permanent gauges.
