* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. Check the cover of the fuse box; it often has a diagram showing the location of the relays. Look for a relay labeled "fuel pump," "EFI," or something similar.
* Under the dash: Less common, but some models placed relays under the dashboard in a secondary fuse panel or relay center.
* Power Distribution Center (PDC): Many Dodge vehicles used a Power Distribution Center, which is essentially a larger fuse box and relay center. This might be located under the hood or even inside the cabin, often under the dash.
To find it, I strongly recommend:
1. Consult your owner's manual: This is the most reliable source. The diagram should clearly show the location of the fuel pump relay.
2. Use a wiring diagram: A wiring diagram specific to your van's year, engine, and options will show the location and circuit of the fuel pump relay. You can often find these online through automotive repair websites (some may require a paid subscription).
3. Check online forums: Search online forums dedicated to Dodge B-150s (or Ram vans, as the B-series was replaced by the Ram van line). Owners might have posted pictures of their fuel pump relay locations, especially if it's been a common issue.
Important Note: Before working on your vehicle's electrical system, disconnect the negative terminal of your battery to prevent accidental short circuits.
