Installing a new fuel pump relay is not to bad of a job. You can try direct power to the fuel pump to see if the pump works.
See below
Here is the fuel pump location for a newer model

My Cadillac runs perfect on all short trips, but after a longer trip (60 min. Or more), it will not start and is not getting fuel. I replaced the filter, and am now trying to locate the fuel relay switch. I have a manual that says it is beside the fuse box, which it isn`t. I went to the GM dealer, and they said it was on the firewall, which it isn`t. So I have a new relay and nowhere to put it.

Its on the firewall, under a black cover made of plastic,
there are 3 of them there, and some fuses, I dought this is your prob, is there a ck engine lite on? Need codes, push off and warmer on heater controls, and they display on heater assy, write them down, with out looking at it I would say your prob is in the distributor, cam sensor or pick up coil

Thanks for your advice. I tried the codes the last time my car wouldn`t start. I got a BCM code 32 and 48. The code 32 is my MAP sensor circuit open. Should I be replacing it instaed of the relay. I found the relay behind the glove compartment.

Did you look for it underhood in a fusebox or on a bracket? Here's a pic from book. #3 is the pump relay.

I need to find out what the fuel pump relay looks like. I found all of the relays under the dashboard and I don't know how to tell which ones which. I have got a 4.1 L V8 Cadillac Coupe Deville 1983 model. Its got digital fuel injection if that makes a difference. Thanks for your time.

I am looking for the fuel pump relay because there is a problem with fuel getting to the engine. The gas tank is not pumping gas at all. I am hoping that it is not the fuel pump. But I am trying to go with the cheapest things first. The reason I need to find the fuel pump relay is because I need to check it and see if it is plugged in or if there even is one.
