2013 Dodge Grand Caravan Fuel Pump Relay: Complete Guide to Location, Symptoms, and Replacement

The bottom line: If your 2013 Dodge Grand Caravan cranks but won’t start, the fuel pump relay is often the culprit. It is located inside the engine compartment fuse box, also known as the Power Distribution Center (PDC), on the driver’s side near the battery. The relay itself is a standard ISO mini relay, typically found in slot #8 (K8). Before replacing the relay, you should also be aware that a larger issue involving the Totally Integrated Power Module (TIPM) may be at play, and in some cases, a recall or external relay bypass kit is the permanent fix.

Where Is the Fuel Pump Relay Located?

The fuel pump relay on a 2013 Dodge Grand Caravan is housed in the Power Distribution Center (PDC) under the hood. This PDC is a large black plastic box mounted on the driver’s side fender well, positioned near the battery and the air filter housing . To access it:

  • Open the hood and locate the PDC.
  • Lift off the large black plastic cover by pulling it straight upward.
  • Flip the cover over to view the engraved layout diagram. This diagram identifies every fuse and relay slot inside the box.
  • Look for the relay labeled “F/PMP,” “FUEL PUMP,” or similar. For the standard 3.6L V6 engine, the fuel pump relay is most commonly located in slot #8 (K8) .

The relay itself is a standard ISO mini relay, about 1.5 inches long, with a 4-pin or 5-pin cube-shaped black plastic body . If the diagram on the cover is missing or worn, consult your owner’s manual or a reliable online source for your specific model year.

Common Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay can cause several distinct problems. The most common symptom is a no-start condition: the engine cranks but does not fire up because the fuel pump is not receiving power. If you turn the ignition to the “ON” position (before cranking) and do not hear a brief humming or buzzing sound from the rear of the van near the fuel tank for about 1-2 seconds, the relay (or the pump itself) is suspect .

Other symptoms include:

  • Intermittent starting issues: The vehicle may start on the second or third attempt, or it may stall unexpectedly while driving. A bad fuel pump relay can cause the engine to stall without warning, leading to a dangerous situation if it happens on the road .
  • Unusual humming or buzzing sounds: If you hear a buzzing noise from the fuel pump area, it may indicate the relay is struggling to provide proper power .
  • Check engine light: In some cases, a bad fuel pump relay can set a diagnostic trouble code (DTC), such as P0230, which relates to the fuel pump relay circuit .
  • Battery drain: If the relay fails in the “closed” (stuck on) position, the fuel pump will run continuously, draining the battery and leaving you with a no-start condition .

How to Test the Fuel Pump Relay

Before buying a replacement, you can test the relay yourself. There are two simple methods:

1. Swap with a Known Good Relay

The Grand Caravan’s PDC houses several identical relays, such as the horn relay, radiator fan relay, and A/C compressor clutch relay. You can swap one of these to test the fuel pump relay :

  • Turn off the ignition.
  • Pull out the suspected fuel pump relay from slot #8.
  • Locate another relay in the box with the same part number (e.g., the horn relay).
  • Remove that known good relay and plug it into the fuel pump relay socket.
  • Turn the ignition key to the “ON” position (not “Start”). Listen near the rear of the van for the distinct 1-2 second humming sound of the fuel pump priming.
  • If you hear the pump run with the swapped-in relay, your original fuel pump relay is faulty. If you still hear nothing, the problem may be the fuel pump itself, a blown fuse, wiring, or the TIPM .

2. Use a Multimeter

If you have a digital multimeter, you can perform a more definitive electrical test :

  • Remove the relay from its socket.
  • Set your multimeter to measure Ohms (resistance).
  • Check continuity between terminals 85 and 86 (the control coil terminals). You should see a reading between 60-100 ohms. No reading indicates a blown coil inside the relay.
  • Next, check for continuity between terminals 30 and 87 (the high-current switch terminals). There should be no continuity (infinite resistance) in the relay’s resting state.
  • Apply 12 volts directly to pins 85 (positive) and 86 (ground). You should hear a distinct click, and the multimeter should now show continuity (very low or zero Ohms) between pins 30 and 87. No click or no continuity means the switch contacts are damaged or stuck open .

The Bigger Issue: The TIPM (Totally Integrated Power Module)

Here is where things get complicated on the 2013 Dodge Grand Caravan. The fuel pump relay is integrated into the Totally Integrated Power Module (TIPM). The TIPM is a sophisticated fuse box and control unit that handles many electrical functions, including the fuel pump. The relay itself is soldered onto the TIPM’s circuit board and is not a separately replaceable plug-in component like a standard relay .

In many cases, a failing fuel pump relay is actually a symptom of a failing TIPM. The internal relay driver fails, preventing the TIPM from properly controlling the fuel pump relay. If you have replaced the relay and the problem persists, the TIPM is likely the culprit . A new TIPM from a dealer can cost between $800 and $1,500 or more .

Safety Recall V62 / NHTSA 19V-813

There is a known safety recall (V62 / NHTSA 19V-813) for 2011-2013 Dodge Durango and Jeep Grand Cherokee vehicles, which are built on the same platform and share the same TIPM design. The recall addresses a fuel pump relay that is susceptible to silicon contamination, which can cause the relay to fail and result in a no-start or engine stall condition . While the official recall does not specifically list the 2013 Dodge Grand Caravan, the same TIPM design is used across many Chrysler/Dodge vehicles from that era, and owners have reported similar issues. If you are experiencing symptoms, it is worth checking with your local dealer to see if your vehicle is covered under any related service campaign.

How to Replace the Fuel Pump Relay (If It Is a Standard Plug-In Type)

If your vehicle has a standard external plug-in relay (which is the case for some later models or after recall repairs), the replacement process is straightforward:

  1. Safety first: Park the vehicle in Park, turn off the ignition, and disconnect the negative (-) battery cable. Loosen the nut on the clamp and lift it off the terminal, securing it away from contact .
  2. Locate the relay: Open the PDC cover and locate the fuel pump relay in slot #8 (K8).
  3. Remove the old relay: Pull the relay straight out of its socket. If it is tight, wiggle it gently.
  4. Install the new relay: Grab your replacement ISO mini relay. Ensure it is an exact match for the original – same physical pin configuration (4-pin or 5-pin) and amperage rating (typically 30-40A). Insert the new relay firmly into the empty socket, orienting it correctly so the pins align perfectly. Push down until it seats fully .
  5. Reconnect the battery: Reconnect the negative battery cable.
  6. Test the repair: Turn the ignition key to the “ON” position (not “Start”). Listen for the fuel pump priming sound. If you hear it, start the engine and verify it runs normally.

The External Relay Bypass: A Cost-Effective Alternative

If you have confirmed that the TIPM’s internal relay driver has failed, you do not necessarily need to replace the entire TIPM. A fuel pump relay bypass kit is a common and effective workaround. This kit bypasses the faulty internal TIPM relay driver and provides a new, independent circuit for the fuel pump relay .

These kits are readily available online or at auto parts stores and typically include a new relay, wiring harness, and instructions. Installation involves connecting the bypass kit’s relay to a switched 12V power source, splicing into the fuel pump power wire, and grounding the relay. While this is a more involved DIY project than swapping a relay, it is still manageable for someone with basic automotive electrical knowledge. Many owners report that this fix saves them hundreds of dollars compared to replacing the TIPM .

Recommended Replacement Parts

If you need to replace the fuel pump relay itself, look for a standard 12V 30-40A ISO mini relay. For the TIPM bypass, you can purchase a specific bypass kit designed for Chrysler/Dodge vehicles from 2008-2016. These kits are available from brands like WATERWICH, FUSCH, and CARBBIA, and are compatible with the 2013 Dodge Grand Caravan .
