where is the fuel pressure switch and the fuel pump relay? on 1998 Cadillac Seville STS

Asked by for the 1998 Cadillac Seville STS
In the rear fuse box check the 20 Amp fuse marked fuel pump, the fuel pump relay needs to see oil pressure from a pressure switch on the engine, fuel pump relay is also in the trunk fuse box. There is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
Circuit is easy to follow.
