2004 Dodge Ram 1500 Fuel Pump Fuse Location: A Complete Guide

If your 2004 Dodge Ram 1500 won't start or has trouble running, the fuel pump fuse is often the first thing to check. On this truck, the fuel pump fuse is located in the engine compartment fuse box, and it's fuse number 17, a 20-amp MINI fuse.

The fuse box is positioned near the battery on the driver's side of the engine bay. It's a black rectangular box with a removable cover. When you open the hood, you'll see it clearly marked. The cover has a diagram printed on its underside that identifies each fuse and relay.

How to Find and Check the Fuel Pump Fuse

Here's a step-by-step approach to locating and testing the fuel pump fuse on your 2004 Ram 1500:

  1. Open the hood. Pull the hood release lever inside the cab, near the driver's side footwell. Then reach under the center of the grille and press the hood latch to fully open the hood.

  2. Locate the fuse box. Look near the left front fender, close to the battery. You'll see a black plastic box labeled "Fuse and Relay Center" or "Power Distribution Center."

  3. Remove the cover. There's a plastic nut holding the cover in place. Unscrew it by hand and lift the cover off.

  4. Identify fuse 17. On the underside of the cover, there's a label that shows the location and function of each fuse. Look for fuse number 17. According to the fuse box diagram, this is a 20-amp MINI fuse that powers the fuel pump relay, the compass/mini trip computer, and the Sentry Key Immobilizer Module.

  5. Check the fuse. The fuse box contains a small plastic fuse puller tool. Use this tool to grip the fuse and pull it straight out. Hold the fuse up to the light. You should see a continuous metal strip inside. If the strip is broken or melted, the fuse is blown.

  6. Test with a multimeter (optional). For a more reliable check, you can use a multimeter set to measure continuity. Touch the probes to the two metal terminals on top of the fuse. If you hear a beep or see a reading, the fuse is good. No reading means it's blown.

What to Do If the Fuel Pump Fuse Is Blown

If you find that the 20-amp fuse for the fuel pump is blown, don't just replace it and hope for the best. A blown fuse is usually a symptom of a bigger problem, not the problem itself. Here's what you should do:

1. Replace the fuse with the correct amperage.
Always use a 20-amp MINI fuse as a replacement. Never use a fuse with a higher amperage rating. Doing so can cause serious damage to your truck's electrical system or even start a fire.

2. Look for the underlying cause.
If the new fuse blows again right away, there's a short circuit or a failing component somewhere in the fuel pump circuit. Common causes include:

  • A failing fuel pump that's drawing too much current.
  • A damaged wire or connector in the wiring harness that runs along the frame rail to the fuel tank.
  • A faulty fuel pump relay.

3. Check the fuel pump relay.
The fuel pump relay is also located in the under-hood fuse box. On 2004 models, it's often labeled as relay number 58 or is marked with a fuel pump symbol. You can test the relay by swapping it with an identical one from a non-essential system like the horn relay. If the fuel pump starts working after the swap, the original relay is bad.

4. Listen for the fuel pump.
After replacing the fuse and checking the relay, turn the key to the "ON" position (don't start the engine). You should hear a faint buzzing sound coming from the rear of the truck for a couple of seconds. That's the fuel pump pressurizing the system. If you don't hear that sound, the pump itself may be dead.

Other Common Fuel Pump Fuse Problems

Many Ram 1500 owners experience similar issues. Here are a few common scenarios and what they mean:

The fuel pump keeps running after the truck is shut off.
This is a known problem on some Ram models. It's usually caused by a stuck fuel pump relay inside the Totally Integrated Power Module (TIPM). The relay gets stuck in the "on" position, which can drain the battery overnight.

The truck cranks but won't start.
If the engine turns over but never fires up, and you've confirmed the fuse is good, the issue is likely with the fuel pump itself or the fuel pump relay. A quick test is to spray starting fluid into the throttle body. If the engine briefly runs, you have a fuel delivery problem.

There is no power to the fuel pump.
Check the wiring harness connector on top of the fuel pump for corrosion or pushed-out pins. Also inspect the main harness connector at the TIPM, which is the large electrical center in the engine bay.

When to Consider Fuel Pump Replacement

If you've checked the fuse, swapped the relay, and still don't hear the fuel pump running, it's very likely that the pump itself has failed. On the 2004 Dodge Ram 1500, the fuel pump is located inside the fuel tank. It's part of a single assembly that includes the pump, filter, and fuel level sending unit.

Here are the most common symptoms of a failing fuel pump:

  • Hard starting: The engine cranks for a long time before it fires up.
  • Sputtering at high speeds: The truck loses power or jerks when you're driving on the highway.
  • Loss of power under load: The engine struggles when climbing hills or towing.
  • Whining noise from the fuel tank: A loud, high-pitched sound coming from the rear of the truck.
  • Engine stalling: The truck dies unexpectedly, especially in hot weather.

If you're experiencing any of these symptoms and the fuse is in good shape, it's time to think about replacing the fuel pump.

Final Thoughts

The 2004 Dodge Ram 1500 fuel pump fuse is easy to find once you know where to look. It's a 20-amp MINI fuse located at position number 17 in the under-hood fuse box. This box is right next to the battery on the driver's side of the engine compartment.

Always start your diagnosis with the simple things. Check the fuse first. If it's blown, replace it with the correct 20-amp fuse and look for the root cause. If the fuse is good but you still have no fuel delivery, check the relay, the wiring, and finally the pump itself.
