How to test and replace a fuel pump relay?

Luckily, fuel pump relays are easy to test and replace on your own. Start by taking the fuel pump relay out of your vehicle so you can clean and inspect it. After that, you can use a multimeter to check the resistance going through the relay’s circuit to see if it’s faulty or not. Part 1

Where is the ground wire on a fuel pump relay?

There is a brown wire ground wire at the bottom right of the fuel pump relay socket that tends to push back instead of connect when inserting the relay. Reaching behind the relay box will indicate whether the spade connector has pushed back or not.

What are the signs of a bad fuel pump relay?

The most common sign of a bad fuel pump relay is an engine that cranks but doesn’t start. A fuel pump relay will typically fail in the open position, preventing voltage from reaching the fuel pump.

How many pins are on a fuel pump relay?

Generally there are four pins (terminals) on the fuel pump relay. One is for input voltage, one is the ground pin, one is the load pin that goes to the fuel pump, and one goes to the battery.

How do I know if my fuel pump relay is working?

Grab the relay firmly on either side and pull it straight up and out from the terminals of the fuse box. If the relay doesn't pull out right away, try rocking it back and forth to loosen the connection. You won't be able to start your engine after you remove the relay because the fuel pump won't work.

How do you test a fuel pump relay socket?

Set your digital multimeter to the lowest range on the Ohms scale or set it to 'continuity. ' Then, connect one lead to one of the power circuit pins, and connect the other lead to the other power terminal. Your meter should read infinite (OL, open load) resistance.

Is a fuel pump relay supposed to click?

Step 4: The fuel pump relay will emit a clicking or buzzing sound when turning the key in the ON position. If you can't hear it inside the vehicle (even if the hood is open), have a friend or assistant help you out. If you can't hear a clicking sound in the fuel pump relay, you'll need to test it to be sure.

How do you tell if a relay is bad with a multimeter?

Grab a multimeter and set it to Ohms. Touch the leads across the electromagnet coil pins and measure resistance. Anywhere from 50-120 ohms is OK. Out of range or open means a bad electromagnet coil winding and time for a new relay.

What will a bad fuel pump relay do?

If the relay fails slowly, then you might notice engine performance symptoms over time. For instance, as the fuel pump relay begins to falter, its ability to power the fuel pump dampens, which can lead to engine stalling when the engine cannot receive enough fuel for combustion.

How do you test a relay with a multimeter?

Take the leads of the multimeter and connect them across the coil terminals of the relay. For a normal coil, the multimeter should read anywhere between 40Ω to 120Ω. If the coil is damaged i.e., it is open, the meter shows out of range and you have to replace the relay.

Can a fuel pump relay work intermittently?

Yes, a fuel pump relay could work intermittently for the following reasons: Loose terminals – If there is no tight connection between the positive and negative terminals and the coils (they may turn out to be loose), it can cause problems like the pump not starting or working at times.

How to find fuel pump relay?

Step 1 – Locate the Fuel Pump Relay. First, make sure that you have enough light and room to work. Then, open your vehicle's hood and find the fuse panel. The majority of vehicles made today have the fuel pump relay located near here, and the fuel pump relay should look like a small plastic box with four to five electrical terminals.

What happens when a fuel pump relay fails?

The most common parts to burn out or break include the contact and the coil. When either of these begin failing, the current to the electrical circuit will be also fail. This means your fuel pump will cease to function properly.

What is the noise coming from the fuel pump relay?

You should also hear a clicking noise coming from the fuel pump relay. This noise is the solenoid inside the relay pulling it shut to connect the two posts together.

How to test a relay?

You want to use either a 12V battery or power supply to test the relay. Connect your ground connection on the power supply to the ground pin on the relay.

How to connect a multimeter to a relay?

Connect your multi-meter or ohmmeter probes to the relay. One probe should connect to the pin that goes to the fuel pump, and the other should connect to the pin that goes to the battery.

How do you check if a fuel pump relay is bad?

Relays are used to turn electrical currents on and off. They help extend the life of switches by preventing high amounts of electricity from going through a switch.

Where is the fuel pump relay located?

Usually, you can find it inside the power center under the hood or the dashboard and side kick panels.

What does the buzzing sound on a fuel pump mean?

The buzzing sound also indicates that the pump pressures the fuel system.

How to diagnose a fluke 88?

You can diagnose the problem by testing it with a multimeter. For advanced users, we highly recommend the Fluke 88 V/A KIT Automotive Multimeter Combo Kit.
