Where is the fuel pump relay for a 1990 Buick Reatta located?
The 1990 Buick Reatta fuel pump relay isn't located in a standard fuse box like many cars. Instead, it's integrated into the Body Control Module (BCM). There isn't a separate, easily replaceable relay you can swap out. If you're having fuel pump issues, the problem likely lies within the BCM itself or its related wiring.
