It is a lot easier to locate the fuse for the fuel pump relay than it is to locate the fuel pump relay. The cover on the fuse box will tell you which fuse it is.
It is tougher than one might think to identify which relay controls what. Alldata does a pretty good job of identifying them if you have access to that. Otherwise, you are pretty much stuck with manually activating different systems while someone puts their finger on the relays to see which one clicks.
