1996 Ford Explorer Fuel Pump Fuse: Complete Location and Troubleshooting Guide
Short answer: The 1996 Ford Explorer fuel pump is protected by a 20 amp maxi-fuse located in the Power Distribution Box under the hood, not a standard blade fuse in the interior fuse panel. This fuse powers the fuel system and anti-theft system, and it sits in the first row from the driver's side, sixth position from the firewall end. If your fuel pump isn't getting power, start by checking this fuse, the fuel pump relay, and the inertia switch before assuming the pump itself is bad.
Understanding the Fuel Pump Electrical System
The 1996 Ford Explorer's fuel pump circuit is more complex than just a single fuse. There are actually three main components you need to understand: the fuel pump fuse, the fuel pump relay, and the inertia switch. Each plays a different role, and knowing which one is causing the problem can save you hours of unnecessary work.
The fuel pump itself is located inside the fuel tank. To access it, you would need to drop the tank, which is a major job. That's why it's so important to check the simpler, cheaper components first. Many owners end up replacing the fuel pump only to find out the real problem was a blown fuse or a tripped inertia switch.
Where Is the Fuel Pump Fuse Located?
For the 1996 Ford Explorer, the fuel pump fuse is not in the interior fuse panel under the dashboard. It is located in the Power Distribution Box (PDB) under the hood. This box is near the brake fluid reservoir on the driver's side of the engine compartment.
The specific location inside the Power Distribution Box is as follows:
- Fuse type: It is a 20 amp maxi-fuse, which is larger than the standard blade fuses you see in the interior panel.
- Row position: It is in the first row from the driver's side of the PDB.
- Position within the row: It is the sixth maxi-fuse from the firewall end of the Power Distribution Box.
- What it powers: This fuse protects the fuel system and the anti-theft system together.
It is important to note that some sources also mention a fuse for the fuel pump relay coil. According to detailed fuse box diagrams for the 1996 Explorer, the interior fuse panel under the dash has a fuse that feeds the PCM system, which includes the fuel pump relay coil. Fuse #13 in the interior panel is a 15 amp fuse that powers the PCM system, stoplamps, 4-wheel drive, anti-lock brake, speed control, and trailer tow. This fuse is different from the main fuel pump power fuse under the hood.
The Fuel Pump Relay: What You Need to Know
The fuel pump relay is also located in the Power Distribution Box under the hood. It is one of the three large relays in the box. It sits in the second row from the driver's side, and it is the second large relay from the front of the box. The relay is responsible for switching the high current to the fuel pump on and off.
If the relay fails, the fuel pump will not receive power even if the fuse is good. You can test the relay by swapping it with a known good relay of the same type from a non-essential circuit, such as the wipers or headlights. If the fuel pump starts working after the swap, the relay was bad. This is a simple and effective way to diagnose the problem without any special tools.
The Inertia Switch: A Common Culprit
The 1996 Ford Explorer has an inertia switch that acts as a safety device. It cuts power to the fuel pump in the event of a collision. This switch is located in the front passenger footwell, in the corner, above the carpet and below the dash. It is a small switch, usually red, that can be reset by pressing a button on top.
A tripped inertia switch is a common cause of a no-start condition that people often mistake for a bad fuel pump. If the switch has been tripped, the fuel pump will not run at all. Before you go any further with your diagnosis, check this switch. Simply press the reset button and try starting the engine. If the vehicle starts, the problem was a tripped inertia switch all along.
Step-by-Step Troubleshooting Guide
If your 1996 Ford Explorer cranks but won't start, and you suspect the fuel pump is not getting power, follow these steps in order. This approach will help you identify the problem quickly and avoid unnecessary repairs.
Step 1: Check the Inertia Switch
Start with the easiest check first. Locate the inertia switch in the front passenger footwell. Press the reset button firmly. Try to start the engine. If it starts, you are done. If it does not start, move on to step 2.
Step 2: Inspect the 20 Amp Maxi-Fuse Under the Hood
Open the Power Distribution Box under the hood. Look for the 20 amp maxi-fuse in the first row from the driver's side, sixth position from the firewall end. Pull the fuse out and look at it. A blown fuse will have a broken or melted wire inside the transparent casing. If it is blown, replace it with a new 20 amp maxi-fuse. Do not use a higher amperage fuse, as this can cause damage to the wiring or start a fire.
Step 3: Check the Interior Fuse #13
Open the interior fuse panel under the dashboard on the driver's side. Locate fuse #13. This is a 15 amp fuse that feeds the PCM system and the fuel pump relay coil. If this fuse is blown, the fuel pump relay will not engage, and the pump will not get power. Replace it if necessary.
Step 4: Test the Fuel Pump Relay
The fuel pump relay is in the Power Distribution Box under the hood. It is a large relay in the second row from the driver's side, second from the front. Find a relay of the same type in the same box that is for a less critical system, like the horn or wipers. Swap the relay with the fuel pump relay. Try to start the engine. If it starts, the fuel pump relay is bad and needs to be replaced.
Step 5: Check for Power at the Fuel Pump Connector
If all the fuses and relays are good, you need to test for power at the fuel pump itself. This is more involved because the pump is in the fuel tank. You will need to access the fuel pump electrical connector. With the ignition turned to the ON position, use a multimeter or test light to check for 12 volts at the connector. If you have power, the pump itself is likely bad. If you do not have power, the problem is in the wiring between the relay and the pump.
Important safety note: Always disconnect the negative battery cable before working on any electrical components. Gasoline is highly flammable, so work in a well-ventilated area and keep any sources of ignition away from the vehicle.
Common Problems and What They Mean
A blown fuse rarely happens for no reason. If you replace a fuel pump fuse and it blows again immediately, there is a short circuit somewhere in the system. This could be caused by chafed wires leading to the fuel pump, a failing fuel pump motor that is drawing too much current, or a problem with one of the other components on the same circuit.
If the fuse blows when you first turn the key, the short is likely between the battery and the relay, or in the relay itself. If the fuse blows after the engine has been running for a while, the problem is more likely in the fuel pump or the wiring near the tank.
For the 1996 Explorer, one common issue is that the wiring to the fuel pump can chafe against the body of the vehicle over time, especially near the fuel tank. This can cause a short that blows the fuse. Inspecting the wiring harness from the frame to the top of the fuel tank can reveal this problem.
When to Replace the Fuel Pump
If you have checked all the fuses, relays, and the inertia switch, and you have confirmed that power is reaching the fuel pump connector but the pump is not running, the fuel pump itself is likely bad. Before you drop the tank, you can also listen for the pump. When you turn the key to the ON position (but do not start the engine), you should hear a brief humming sound from the rear of the vehicle for about 2 to 3 seconds. This is the fuel pump priming. If you do not hear this sound, the pump is not getting power or the pump is dead.
Replacing the fuel pump on a 1996 Ford Explorer is a significant job. It involves draining the fuel tank, dropping the tank, removing the pump assembly, and installing a new one. Many owners find this to be physically demanding work, especially if they are working on the ground without a lift. If you are not comfortable doing this job yourself, it is worth paying a shop to do it.
