2014 Ford F150 Fuel Pump Relay Location – Find And Fix Your No-Start
The 2014 ford f150 fuel pump relay location is inside the Power Distribution Box, which is the large fuse box situated under the hood directly above the radiator. Specifically, you are looking for Relay 27, a small black plastic cube that controls power delivery to the fuel system. Identifying this component is the first step in diagnosing a truck that cranks but refuses to start.
There is nothing quite as frustrating as climbing into your truck, turning the key, and hearing the engine crank endlessly without firing up. If you own a 2014 Ford F-150, you are likely dealing with a fuel delivery issue that often points back to the electrical system.
Finding the 2014 ford f150 fuel pump relay location is a critical skill for any owner who wants to avoid expensive diagnostic fees at a dealership. In this guide, we will walk through the exact steps to locate, test, and replace this relay while addressing a common design flaw you must know about.
Whether you are a weekend DIYer or an off-road enthusiast stranded on a trail, understanding your truck’s fuse box layout is essential for reliability. Let’s dive into the engine bay and get your 5.0L, 3.5L EcoBoost, or 6.2L V8 back to life.
Identifying the 2014 ford f150 fuel pump relay location
The first thing you need to do is pop the hood and secure it with the prop rod or ensure the struts are holding it firmly. To find the 2014 ford f150 fuel pump relay location, look toward the front of the engine compartment, centered just above the radiator cooling fans.
You will see a long, black plastic rectangular box; this is the Power Distribution Box. It houses the high-current fuses and relays that manage the truck’s most vital electrical functions, including the fuel pump circuit.
To open the box, press the plastic tabs on the sides and lift the cover upward. On the underside of this lid, you will find a printed diagram, though it can be difficult to read after years of heat and dust accumulation.
Finding Relay 27
In the 2014 model year, the fuel pump relay is designated as Relay 27. It is a small, square relay that sits among several others of similar size.
When you are looking at the fuse box from the front of the truck, Relay 27 is typically located in the middle row of the larger relays. It is responsible for closing the circuit that sends 12-volt power back to the fuel pump driver module.
If this relay fails, the fuel pump will never receive the signal to prime. This results in an engine that “turns over” perfectly fine but never actually catches fire because there is no gasoline reaching the injectors.
Understanding the Difference Between the Relay and the Fuse
It is very common for F-150 owners to confuse the fuel pump relay with the fuel pump fuse. While they work together, they serve very different purposes in your electrical system.
The relay is an electromagnetic switch. When you turn your key to the “On” position, a small amount of current flows through a coil in the relay, which pulls a larger contact shut to move high-amperage power to the pump.
The fuse, on the other hand, is a sacrificial link. It is designed to “blow” or melt if there is a sudden surge in electricity, protecting the expensive fuel pump from burning out.
The Infamous Fuse 27 Problem
If you are searching for the 2014 ford f150 fuel pump relay location, you absolutely must check Fuse 27 as well. On the 2009–2014 F-150s, this specific fuse is known for a major design flaw.
The fuse itself is a 20-amp “mini” fuse. Because the fuel pump draws a consistent, high load, this tiny fuse can become hot enough to melt its plastic casing and the fuse box socket it sits in.
Often, the relay is perfectly fine, but the fuse has melted just enough to lose contact. This creates an intermittent “no-start” condition or causes the truck to stall while driving at highway speeds.
Symptoms of a Failing Fuel Pump Relay
How do you know if the relay is actually the problem? Relays usually fail in one of two ways: the internal coil burns out, or the metal contact points inside become “pitted” or charred from years of use.
One of the most common symptoms is a crank, no-start condition. You hear the starter motor working hard, but the engine sounds “hollow” because there is no combustion happening.
Another symptom is the lack of a “hum” when you turn the key. Normally, when you turn the ignition to the “Run” position, you should hear the fuel pump prime for two seconds from under the truck bed.
Intermittent Stalling and Hard Starts
If the 2014 ford f150 fuel pump relay location is housing a relay with burnt contacts, you might experience intermittent stalling. The truck might run fine for twenty minutes and then suddenly die as if you pulled the plug.
You might also notice “hard starting,” where the truck takes five or six seconds of cranking before it finally stumbles into life. This happens when the relay is struggling to maintain a solid electrical connection.
If you are off-roading or towing a heavy trailer, these symptoms can be dangerous. Heat increases electrical resistance, making a failing relay even more likely to quit when the engine bay is hot.
Step-by-Step Guide to Testing the Relay
Before you go out and buy a new relay, you can perform a few simple tests. You don’t need to be a professional mechanic to do this; you just need a little patience and perhaps a multimeter.
- The Finger Test: Have a friend turn the ignition key to “Run” (don’t start the engine) while you keep your finger on Relay 27. You should feel a distinct “click” as the internal magnet moves.
- The Swap Test: This is the easiest field fix. Find another relay in the box with the same part number—usually the rear defrost or blower motor relay—and swap it into the 2014 ford f150 fuel pump relay location.
- Check for Power: Use a test light or multimeter to ensure power is reaching the relay socket. If there is no power at the socket, your problem is likely a blown fuse or a broken wire further up the line.
If you swap the relay and the truck starts immediately, you’ve found your culprit. Make sure to buy a high-quality OEM Motorcraft relay rather than a cheap generic one to ensure longevity.
Using a Multimeter for Precision
If you want to be 100% sure, set your multimeter to the Ohms (Ω) setting. Touch the probes to pins 85 and 86 on the relay; you should see a resistance reading (usually between 50 and 100 ohms).
If the reading is “OL” (Open Loop), the internal coil is broken. Next, check for continuity between the power pins while the relay is energized. If the circuit doesn’t close, the relay is junk.
Always perform these tests with the battery connected but the engine off. Safety is paramount when working around fuel systems and moving engine parts.
The Permanent Solution: Fuse 27 Relocation Kit
As mentioned earlier, finding the 2014 ford f150 fuel pump relay location often leads owners to discover a melted Fuse 27. If you see black soot or melted plastic around that fuse, a simple replacement won’t fix it.
Ford actually released a Technical Service Bulletin (TSB) for this exact issue. The fix involves moving the fuel pump circuit from the tiny “mini” fuse slot to a much larger, more robust J-Case fuse slot in the same box.
You can purchase a “Fuse 27 Relocation Kit” (Part number EL3Z-14293-A). This kit includes a heavy-duty wire, a new terminal, and a larger fuse that can handle the heat of the fuel pump’s electrical draw.
Why You Should Do This Proactively
Even if your truck is running fine today, if you have a 2014 F-150, you should inspect Fuse 27 immediately. Pull the fuse out and look at the metal legs; if they look discolored or “burnt,” the failure is coming.
Installing the relocation kit requires cutting one wire and soldering or crimping a new lead into the bottom of the fuse box. It takes about 45 minutes and provides permanent peace of mind.
Many off-roaders perform this mod as “preventative maintenance.” The last thing you want is for a $2 fuse to melt while you are miles away from cell service in the middle of a trail.
Other Potential Failures: The Fuel Pump Driver Module
If you have checked the 2014 ford f150 fuel pump relay location and the fuse is perfect, but the truck still won’t start, the next suspect is the Fuel Pump Driver Module (FPDM).
The FPDM is a small computer that sits on a crossmember above the spare tire. On older F-150s, these were famous for rotting out because their aluminum housing would touch the steel frame and corrode.
By 2014, Ford added rubber stand-offs to prevent this, but the modules can still fail internally. If the relay is clicking and the fuse is good, the FPDM might not be passing that power to the pump.
Checking the Spare Tire Area
To inspect the module, you will need to lower your spare tire. Look for a small black box bolted to the frame rail. Check the electrical connector for corrosion or green crusty buildup.
If you live in the “Salt Belt” where roads are salted in winter, this is a very common failure point. Road spray gets kicked up by the rear tires and coats the module in moisture and salt.
A quick way to test this is to check for power at the fuel pump connector itself. If power reaches the module but doesn’t come out, the module has failed.
Frequently Asked Questions About 2014 Ford F150 Fuel Pump Relay Location
Where exactly is the fuel pump relay located?
The fuel pump relay is located in the Power Distribution Box under the hood, specifically identified as Relay 27. It is a small square relay in the center of the box.
Can I bypass the fuel pump relay in an emergency?
Technically, you can use a “jumper wire” to connect the power pins in the relay socket, but this is not recommended. Doing so keeps the fuel pump running constantly, which can drain your battery or cause a fire hazard if you are in an accident.
What is the part number for the 2014 F-150 fuel pump relay?
The standard part number is FOAB-14B192-AA or the Motorcraft equivalent 8T2T-14B192-AA. Always verify with your VIN at the parts counter, as some heavy-duty models may vary.
Why does my F-150 start sometimes but not others?
This is often a sign of a melting Fuse 27 or a relay with pitted contacts. As the temperature changes, the metal expands and contracts, causing the intermittent connection issues you are experiencing.
Is there a recall for the fuel pump relay?
There was no official safety recall for the relay itself, but there is a well-known Technical Service Bulletin (TSB 15-0137) regarding the melting fuse. Most dealerships will charge for this repair unless you have an extended warranty.
Final Thoughts for the DIY Mechanic
Understanding the 2014 ford f150 fuel pump relay location is more than just a bit of trivia; it is a vital part of owning one of the most popular trucks on the road. By knowing where to look, you can save yourself hundreds of dollars in towing and shop labor.
Always remember to start with the simplest solution first. Check the relay, inspect Fuse 27 for signs of heat damage, and listen for the fuel pump’s hum. Most of the time, the fix is a simple $15 part and ten minutes of your time.
If you find that your fuse box is melted, don’t just put a new fuse in. Invest in the relocation kit to ensure your truck remains reliable for years to come. It is a small price to pay for the confidence that your F-150 will start every time you turn the key.
