Click on the link.
The load side of relay is that line with arrowhead. When the relay is energized that line moves to other terminal. You can see the fuse for load side of relay.
The right side of relay is the control side, has to have voltage and ground. The ground is chassis ground, the voltage should come from pcm.
Now, if you have problem with more than one system, like, no spark--fuel or fuel injector pulse. I look for a rpm signal. I don't know if trouble codes will help, but, I'd check applicable codes, anyway.

SOURCE: 1996 CADILLAC DEVILLE, NO POWER TO FUEL PUMP

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

SOURCE: how to change fuel pump 1990 cadillac seville

The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

SOURCE: How do I replace the

Hello ray......

The fuel pump is located inside the fuel tank. You can access the fuel tank thru the trunk. Inside the trunk and underneath the carpet, there is a access panel. Remove the five screws and lift the access panel. There under the panel you will see the pump. Disconnect it and take it to the auto parts store as they usually want the old one for an exchange.

My 1995 Cadillac Seville fuel pump is working, but my gas gage is not


The fuel gauge is attached to the fuel pump so the pump has to be removed to repair the fuel sending switch. As a general rule, both should be replaced at the same time to save inconvenience and labor expense at a later time.

Location of fuel pump relay on cadillac seville 1991


The fuel pump relay on your 1991 DeVille is in the relay center underneath the passenger side of the dash, to access, take down the sound barrier under the right side of the dash panel (7mm). The third one from the bottom right relay position is for the fuel pump (be sure to count any vacant positions, you may not have all the accessories).However, if you just want to check if it is good, you can run a fused jumper from the positive battery post to the prime connector. The prime connector is green with a red wire (not connected to anything else), It's located underneath a cover on the firewall a few inches inboard of the right hood hinge.

Hi 1994 Seville SLS 4.6.fuel pump relay. Is there any way to test


no do not drill no holes wher the gas tank is.the bast way to drop it is to buy a syphon pump for $10 at walmart and get all the gas out. it is located on top of gas tank. to test a relay . take an old phone charger cut the end off that connects to phone wrap one wire to #86 and other to #85 on the relay terminals . it should click each time you connect the charger to terminals. if u have a multimeter use the continuity seting and check terminals 87 and 30 for continuity. it should only beep with power aplied to #86 and 85
