How to Replace Fuel Pump Relay

9 minutes ago • 0 comments

Recently, my vehicle had some faulty. My friend, a mechanic told me that the fuel pump relay was out of work. So, I intended to replace it by myself.

Automobile relays are composed of a magnetic circuit system, contact system, and restoration mechanism, as indispensable circuit components, such as automobile lights, air conditioners, electric seats, electric doors and windows, ABS devices, etc. have control relays.

Materials Needed • Needle nose plyers • Ratchet with metric and standard sockets • Wheel chocks

Step 1:

Turning on the ignition key ,wait for the gasoline pump to operate. Also, listen for any buzzing or clicking noises coming from the fuel pump relay.

Step 2:

Start the engine. Check that there is oil pressure. An oil light may be the lone signal on some automobiles. When the indicator light turns off, there will be oil pressure.

Park your vehicle on a flat, hard surface. Make sure the transmission is in a park (for automatic transmissions) or first gear (for manual transmissions) (for manuals).

Step 4:

Place wheel chocks around the tires. Because the rear of the car will be raised, the wheel chocks will be around the front tires in this situation. Engage the parking brake to lock the rear tires from moving.

Step 5:

Install a nine-volt battery saver into your cigarette lighter. This will keep your computer activated and your vehicle's settings current. It's fine if you don't have a nine-volt battery saver.

Step 6:

Open the vehicle’s hood to disconnect your battery. Remove the ground line from the negative post of the battery to turn off the power to the fuel pump and sending unit.

Step 7:

Locate the fuel pump relay using the diagram on the fuse box cover.

Using the schematic on the fuse box cover, look for the fuse for the fuel pump relay when you open the fuse box.

Step 8:

Remove the fuel pump relay from the fuse box. Pay attention to how the relay comes out as the new one needs to go in the same way. If your fuse box cover doesn't have any schematics on it, you can look up the engine compartment fuse box diagram in your owner's handbook. The number adjacent to the fuel pump relay is usually stated in the owner's manual so you can discover the number on the fuse box.

Note: You may need to use a pair of needle nose players to pull out the fuel pump relay.
