1995 Toyota Corolla Fuel Pump Relay Location: The Complete Guide
The fuel pump relay on a 1995 Toyota Corolla is located inside the engine compartment fuse box (also called the relay box or junction block), mounted on the driver’s side near the battery. This small but critical component controls power delivery to the fuel pump, and knowing its exact location can save you hours of frustration when your car cranks but won’t start.
For the 1995 model year, Toyota produced the Corolla with either a 1.6L or 1.8L engine. The fuel pump relay location is identical across both engine options . The relay box is a black plastic rectangular unit situated on the left inner fender, close to the windshield washer fluid reservoir. You do not need to remove the battery or any major components to access it.
Why the Fuel Pump Relay Matters
The fuel pump relay acts as an electrical switch. When you turn the ignition key to the “ON” position, the Engine Control Module (ECM) sends a signal to the relay, which then closes the circuit and sends power to the fuel pump located inside the fuel tank . If the relay fails, the pump receives no power, and the engine will crank but not start or run.
Common symptoms of a bad fuel pump relay include:
- The engine cranks normally but does not start
- No audible fuel pump prime sound when you turn the key to “ON” (you should hear a brief whirring from the rear of the car)
- The car starts intermittently or stalls after running for a short time
- The Check Engine Light comes on with fuel system related codes
Step-by-Step Guide to Locate the Relay
1. Open the hood and secure it properly.
Pop the hood latch from inside the driver’s cabin, then release the secondary safety latch under the front of the hood. Prop the hood open.
2. Look at the driver’s side fender area.
Stand on the driver’s side of the car. The relay box is mounted on the left inner fender, directly behind the air cleaner housing and near the battery. It is a black plastic box with a detachable lid .
3. Identify the relay box.
The fuse/relay box is roughly 6 inches by 4 inches. It has a lid that clips on. On the lid, you will see a diagram or labels indicating the position of each relay and fuse. If the diagram is faded or worn, you can still find the relay by its size and shape — it is a square or rectangular relay with four or five pins.
4. Locate the specific fuel pump relay.
Inside the box, the fuel pump relay is typically labeled “FUEL PUMP” or “F/P” on the underside of the lid. If the label is missing, look for a relay that is larger than the rest — the fuel pump relay is usually a standard 4-pin or 5-pin relay, often colored green, black, or brown. In many 1995 Corolla models, it is the second relay from the left in the top row .
5. Confirm you have the right relay.
Turn the ignition key to the “ON” position (do not start the engine). Place your hand on the suspected relay. You should feel a slight click and possibly a vibration as the relay energizes. If you do not feel any activity, the relay may be faulty.
Testing the Fuel Pump Relay
Before you buy a new relay, it is worth testing the old one. This is a simple process that can confirm whether the relay itself is bad or the problem lies elsewhere.
What you need:
- A digital multimeter (set to ohms or continuity mode)
- A 12V test light (optional)
- A small screwdriver to pry open the relay box
Test procedure:
Step 1: Remove the relay.
Grasp the relay firmly and pull it straight out of its socket. It may take a little wiggling, but it should come out without excessive force.
Step 2: Check for power at the socket.
With the relay removed, turn the ignition to “ON.” Use your multimeter or test light to check for 12V at the socket terminals. Consult the wiring diagram for your specific model to identify the power and ground terminals . Typically, one terminal should show battery voltage. If there is no power at the socket, the problem is not the relay — it could be a blown fuse, a bad ignition switch, or a wiring issue.
Step 3: Test the relay coil.
Set your multimeter to ohms. Connect the probes to the two coil terminals (usually terminals 85 and 86 on a standard relay). A good relay coil will show a resistance reading between 50 and 120 ohms. If you get an open circuit (OL) or very low resistance (near zero), the relay is bad.
Step 4: Test the relay contacts.
Connect the multimeter probes to the two switch terminals (usually terminals 30 and 87). The reading should be infinite (open circuit) when the relay is not energized. Now apply 12V power to the coil terminals (85 and 86) using a small battery or power source. You should hear a click, and the resistance between terminals 30 and 87 should drop to near zero ohms. If you do not get a click or the contacts do not close, the relay is faulty.
Step 5: Inspect the relay visually.
Look for any signs of corrosion, melted plastic, or burnt contacts. Even if the relay tests electrically okay, physical damage can cause intermittent failures.
Common Problems and Troubleshooting Tips
Problem: Engine cranks but no start, no fuel pump prime sound.
Start with the relay. Swapping it with a known good relay (like the horn relay, which is often identical) is a quick diagnostic trick. If the car starts with the swapped relay, your original fuel pump relay is bad.
Problem: Relay tests good, but no power to the fuel pump.
The issue may be in the wiring between the relay and the pump, the fuel pump itself, or the ECM. Check the fuel pump fuse (often located in the same relay box or in the interior fuse panel under the dashboard). Also inspect the ground connection for the fuel pump circuit, which is often located behind the rear seat or near the fuel tank.
Problem: Fuel pump runs continuously with key on but engine off.
This indicates a stuck relay where the contacts are welded closed. Replace the relay immediately. A continuously running pump can drain the battery and potentially damage the fuel system.
Problem: Intermittent starting issues.
An intermittent relay may work when cold but fail when hot. If you suspect this, wait until the car fails to start, then tap the relay lightly with a screwdriver handle. If the car starts, the relay is likely failing.
How to Replace the Fuel Pump Relay
Replacing the fuel pump relay on a 1995 Toyota Corolla takes about 5 minutes and requires no special tools.
Step 1: Ensure the ignition is off.
Turn the key to the “OFF” position and remove it from the ignition.
Step 2: Remove the old relay.
Locate the relay box as described above. Pull the old relay straight out of its socket. If it is stuck, gently rock it back and forth while pulling.
Step 3: Install the new relay.
Align the new relay with the socket pins. The relay is keyed — it will only fit one way. Push it down firmly until it clicks into place.
Step 4: Test the new relay.
Turn the ignition to “ON” and listen for the fuel pump prime sound. It should run for 1-2 seconds and then stop. If you hear it, the installation is successful.
Step 5: Close the relay box.
Snap the lid back onto the relay box. Close the hood.
Where to Buy a Replacement Fuel Pump Relay
You can purchase a fuel pump relay from several sources. OEM Toyota parts are available through dealerships or online retailers like Toyota Parts Now . Aftermarket options are also widely available from PartsGeek, AutoZone, and other auto parts stores . Prices typically range from $15 to $40 for a standard relay.
Always verify the part number matches your specific vehicle. The correct relay for a 1995 Corolla with a 1.8L engine is often the same as for other Toyota models of the same era. If you are unsure, provide your VIN number to the parts supplier.
