Look atht e cinter of the firewall and there are several relays and one should have a pink, gray and several other wires which is the fuel pump. ADDED BY A91RSINVEGAS: Just in case, there is a fuse that is often overlooked by so called "mechanics". The diagnoses will be a bad fuel pump, costing hundreds of dollars to replace, then they find out that the new pump doesn't work (but charge you for the new pump anyway). This fuse is directly related to the ECM/fuel pump/oil sending unit. It is located in a small black box connected to the battery by an orange wire. My box was on the fender well near the battery, but I have seen them closer to the fender. Normally when you turn on the key before starting, there is a period of time when all the system lights come on. This is a system test. When I blew the fuse replacing the oil sending unit, the SES (service engine soon light) did not come on during this test, and obviously, the car would not start because the was no power going to the fuel pump.
