Location of fuse for fuel pump on 1998 mercury mystique?

The 1998 Mercury Mystique fuel pump fuse isn't a single, easily identifiable fuse like some other car components. The fuel pump is controlled by the Powertrain Control Module (PCM) and doesn't have a dedicated fuse in the traditional sense. A problem with the fuel pump itself, or the wiring to it, will likely trigger other issues.

Instead of looking for a fuel pump fuse, if you suspect a fuel pump problem, you should:

1. Check the fuel pump relay: This is a more likely culprit than a blown fuse in this system. The relay's location varies slightly depending on the engine, but it's usually found in the underhood fuse box. Consult your owner's manual for the exact location and diagram.

2. Have the system professionally diagnosed: A mechanic can use diagnostic tools to check the fuel pump circuit, PCM, and other components related to fuel delivery. This is the most reliable way to pinpoint the problem and avoid unnecessary parts replacement.

Attempting to directly test the fuel pump's electrical connection can be dangerous due to the high pressure and potential for fuel leaks. It's best left to a qualified mechanic unless you have significant automotive electrical experience.
