2006 Dodge Ram Fuel Pump Fuse: Location, Diagram, and Troubleshooting Guide

The 2006 Dodge Ram fuel pump fuse is located inside the Integrated Power Module (IPM), which is the main fuse box under the hood on the driver's side near the battery . For the 2006 model year, there is no dedicated fuse labeled "fuel pump" in the traditional sense. Instead, the fuel pump circuit is protected by a fuse in the IPM, and the fuel pump relay is built inside the Totally Integrated Power Module (TIPM) . If your 2006 Ram cranks but won't start, the fuel pump fuse and the internal relay are the first things you need to check. This guide walks you through the exact fuse location, how to test the circuit, and what to do when the fuse is fine but the pump still won't run.

Where Is the Fuel Pump Fuse on a 2006 Dodge Ram 1500?

The 2006 Dodge Ram 1500 uses a single engine compartment fuse box called the Integrated Power Module (IPM) . It sits near the battery on the driver's side. Open the hood and look for a black plastic box with a cover that says "Fuse and Relay Center" . To access the fuses, unscrew the plastic nut holding the cover in place .

Important: The 2006 Ram does not have a fuse marked "Fuel Pump" on the fuse box cover . The fuel pump receives power through the TIPM, which contains the fuel pump relay internally . The fuse that supplies power to the fuel pump circuit is often fuse #22 (2A) labeled "IGN Switch Feed" or fuse #28 (10A) labeled "Power Run/Start" . However, the actual fuel pump power path runs through the internal relay inside the TIPM, and a separate fuse may not be directly visible .

For the 2006 model, the recommended approach for a no-start condition is to test the TIPM internal relay first . If you suspect the relay has failed, you can install an external fuel pump relay bypass kit to confirm the diagnosis .

2006 Dodge Ram 1500 Fuel Pump Fuse and Relay Diagram

The 2006 Dodge Ram 1500 IPM contains the following key fuses related to the fuel system and engine start circuit :

  1. Fuse #10 (5A) – Powertrain Control Module (PCM), Transmission Range Sensor, Clutch Interlock Switch. This fuse powers the engine computer that controls the fuel pump.
  2. Fuse #22 (2A) – Ignition Switch Feed. This supplies power to the ignition switch, which in turn powers the fuel pump relay.
  3. Fuse #28 (10A) – Power Run/Start, ABS, RWAL, WCM. This fuse provides power during crank/run to multiple modules, including the fuel pump control circuit.
  4. Fuse #31 (10A) – PCM, Transfer Case Brake. Another fuse that feeds the PCM.
  5. Fuse #33 (10A) – Power Ignition Run Misc. This powers general ignition-run circuits.

The fuel pump relay is not a plug-in relay you can swap like older models (2002–2005) . In the 2006–2008 Rams, the relay is soldered inside the TIPM . If the internal relay fails, you have three options:

  • Replace the entire TIPM (expensive, $700–$1,200 OEM) .
  • Use a remanufactured TIPM from Dorman or a repair service ($300–$600) .
  • Install a TIPM fuel pump relay bypass cable ($25–$50), which restores power to the pump by creating an external circuit .

How to Check the Fuel Pump Fuse on a 2006 Dodge Ram

Follow these steps to check the fuse and relay on your 2006 Ram 1500:

Step 1 – Open the IPM. Pull the hood lever inside the cab, then release the safety latch under the grille . Unscrew the plastic nut on the fuse box cover and lift it off .

Step 2 – Inspect the fuse. Use the fuse diagram printed on the inside of the cover to locate fuse #22 (2A) and fuse #28 (10A) . Pull each fuse using the fuse grabber tool stored in the fuse box . Hold it up to the light to see if the metal strip inside is broken. A blown fuse will have a visible gap or dark burn mark.

Step 3 – Swap or replace the fuse. If a fuse is blown, replace it with a new fuse of the exact same amperage . Using a higher-rated fuse can cause serious electrical damage .

Step 4 – Test the relay circuit. Since the relay is internal, you cannot swap it. Instead, use a multimeter to check for power at the fuel pump connector :

  • Raise the truck safely and locate the fuel pump electrical connector on top of the fuel tank .
  • Disconnect the connector and inspect for corrosion .
  • Have an assistant turn the key to "ON" while you measure voltage at the connector. You should see battery voltage for 2–3 seconds .
  • If voltage is present but the pump doesn't run, the pump motor itself is failing .
  • If no voltage is present, check the wiring (circuit K31) for continuity between the TIPM and the pump .

What to Do When the Fuse Is Good but the Pump Still Won't Run

If the fuses are good and you've confirmed the relay circuit, the problem may be one of these:

1. The internal TIPM relay is dead. This is a very common failure on 2006–2008 Dodge Rams . The easiest test is to install an external bypass kit. If the truck starts, the TIPM relay needs to be replaced or bypassed permanently .

2. The fuel pump motor is worn out. If you have power at the connector but the pump doesn't hum, tap the bottom of the fuel tank with a rubber mallet while an assistant turns the key . If the truck starts, the pump motor is failing and needs replacement .

3. A wiring open circuit. Trace the wiring between the TIPM and the fuel pump. Look for chafed, corroded, or damaged wires. The connector on top of the tank is prone to dirt and mud buildup .

4. A faulty PCM or fuel level sender. Less common, but the Powertrain Control Module can fail to command the fuel pump relay. Also, check the fuel level sender resistance: about 220 ohms empty and 20 ohms full .

Fuel Pump Fuse Location on Other 2006 Dodge Ram Models

The fuse box location is similar across the 2006 Ram lineup, but fuse assignments can vary slightly:

  • 2006 Dodge Ram 1500 Gasoline (3.7L, 4.7L, 5.7L): IPM under the hood near the battery . Fuel pump relay is internal to the TIPM .
  • 2006 Dodge Ram 2500/3500 Diesel (5.9L Cummins): Uses a separate fuel pump relay and fuse #42 (30A) "Diesel PCM" in the IPM .
  • 2006 Dodge Ram with 26-Gallon Tank: The fuel pump module is specific to short-bed, 26-gallon tanks. A complete fuel pump module assembly (e.g., E7186M) includes the pump, sending unit, and strainer .

Always verify your truck's specific fuse map on the inside of the IPM cover or in the owner's manual before replacing fuses .

Common Fuel Pump Problems on the 2006 Dodge Ram 1500

The 2006 Ram 1500 is known for several fuel system issues :

  1. TIPM relay failure – This is the #1 cause of a no-start with a good fuse. The relay is not serviceable and requires either a bypass kit or a new TIPM .
  2. Fuel pump motor failure – The internal electric motor creates an open circuit after high mileage, often around 100,000+ miles .
  3. Corroded fuel pump connector – The connector on top of the tank collects dirt and mud, preventing a good electrical connection .
  4. Failed fuel level sending unit – This causes inaccurate gauge readings even when the pump works fine .

Fuel pressure specification: For 2002–2003 models, the expected pressure is 49–53 PSI at the fuel rail. For 2006 models, the system runs at higher pressure (around 90–110 psi at the pump output) . If pressure reads 0 PSI, the pump is not delivering fuel .

How Much Does It Cost to Fix a Fuel Pump Issue on a 2006 Ram?

If you need to replace the fuel pump or TIPM, here's what you can expect to pay :

  • Fuel pump module (aftermarket): $150–$300
  • Fuel pump module (OEM Mopar): $350–$500
  • TIPM replacement (OEM): $700–$1,200
  • TIPM (remanufactured): $300–$600
  • External relay bypass kit: $25–$50
  • Labor (shop replacement): 2–4 hours at $75–$125/hour, totaling $150–$500
  • Total shop bill: $500–$1,100, with most jobs around $700–$900

A DIY fuel pump replacement costs only about $200–$500 in parts if you do the work yourself . However, replacing an in-tank pump requires dropping the fuel tank or accessing a service panel, which takes 1–4 hours depending on your skill level .
