Where is the fuse for fuel pump located on a 1994 S10 truck?

The fuse for the fuel pump in a 1994 S10 is not in the standard fuse box under the hood. It's usually a 30 amp fuse, but it's often a blade-type fuse located in a separate fuse block, frequently found either near the battery or under the dash. GM's placement was inconsistent across their models in this era.

To find it, you'll need to:

1. Consult your owner's manual: This is the best resource. It should have a diagram of the fuse box layouts and list what each fuse controls.

2. Check the under-hood fuse box carefully: Even though it's unlikely to be there, double-check the entire box, including any secondary fuse panels that might be attached.

3. Look near the battery: There's often an auxiliary fuse box or a block of fuses mounted on the chassis or fender well close to the battery. This is a common location for fuel pump fuses/relays.

4. Inspect under the dash: Some S10s had additional fuse blocks under the dash, sometimes on the driver's side.

5. Look for a fuel pump relay: While not the fuse itself, a bad fuel pump relay can prevent the pump from working. Often, the relay is located in the under-hood fuse box or near the battery. Replacing it is a quick and easy check.

If you can't find it using these methods, it's best to consult a qualified mechanic or a reliable online S10 forum specific to your year and engine (e.g., a forum dedicated to 1994 S10s). Providing the engine size (e.g., 4.3L V6, 2.8L V6) would also help in finding more targeted information online.
