Where is the fuel pump relay switch in a 1986 Toyota supra?

The fuel pump relay location in a 1986 Toyota Supra isn't standardized and depends on the specific model (e.g., whether it's a P-type or MA70). There's no single definitive answer.

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The manual should have a diagram of the fuse box and relay locations.

2. Check the fuse box diagrams: Often found inside the fuse box cover itself, or in a separate compartment nearby (sometimes under the dash or in the engine bay). Look for a diagram that labels the relays. Sometimes the fuel pump relay is labeled, other times it's indicated only by its function.

3. Look in common relay locations: These relays are frequently found in the fuse box under the dash, the fuse box in the engine bay (if present), or sometimes even a separate relay box.

Because there's no single location, a visual inspection is necessary. Search carefully in all potential areas. If you cannot locate it by referring to your owner's manual and looking in the usual relay locations, you may need to consult a Toyota Supra specific repair manual or forum for your specific model.
