Where is it located? I'm installing a fuel pump and need to check the relay...

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 https://www.2carpros.com/questions/cadillac-deville-2000-cadillac-deville-fuel-pump-relay Please let us know happens so it will help others. Best, Ken

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..

Check engine compartment relay block near the washer fluid reservoir...

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..

engine turns over but no fuel coming from injectors in throttle body

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

looks to be under dash pass side interior.

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.

it is on the rely center under the dash as you were describing.

why are you looking for this?? what is the issue??

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.

i am trying to find out and see if there is something electrical going on that could be stopping the car fuel pump from pumping

Did you check under the hood in the relay block?

could not find a relay block under the hood.

on the car the relay block is on the fuzebox
the relay block is under the dash
