Hello, Although I have had so many and worked on more, I can't tell you exactly...3 areas control the Olds V8 fuel injection. Above the parking brake area is the GM normal fuse location. The Bendix control unit in behind the glove box/under passenger kick panel holds the majority of the fuel injection computer "stuff". And on the right front top engine, is a bank of connections, but can't remember if the relay had been moved there yet, as in later Caddy's. With your ear in those areas, listen for the click, and lock for square black plug in relays circa that era. Hope this Helps, AskTrannyMan

Still haven't found the fuel pump relay for the 78 Cadillac elegante. Needless to say the car is still not running I'm getting no gas . I've got spark but no gas. Help help!

same question here: Fuel Pumps are working, the high pressure one only if connected directly, but otherwise it receives no power. can someone tell, if there is a fuel pump relay or a fuel pump fuse somewhere and if-, where it is located. it cannot be, that the voltage only is regluated by the ECU, isn't it? thx for help
