Let's grab our electrical connector, apply a tiny bit of dielectric grease to the connector point and connect it in. You don't wanna overtighten this, so it cracks the plastic. We'll start in both of our bolts, then we'll snug them up. Let's go ahead and line it up with where it needs to go. Okay, friends, now it's time to get our brand new sensor in here. Let's set this aside for now and continue on by removing our two mounting bolts. If you see something in there, well, you either need to service it or replace your pigtail. I always like to take a peek at all my electrical connectors and make sure I don't see any funny colors. After that, give this a nice wiggle and draw it right off. Let's continue on by pressing down on this center tab right here. Now that we have a nice, clear view of the area. Obviously, if you wanted to, you could try to access everything, and more than likely you could probably remove it without taking anything apart, but I'm just gonna hook go ahead and take this off that way there I have plenty of room. Once you're inside there, you'll be able to see it right directly behind this plastic area. To get started on our fuel pump relay module, you wanna go to the left rear wheel well. If the noise is from the fuel pump, failure of the pump is often imminent and you should replace the fuel pump at your earliest convenience.All right, friends. As a fuel pump fails, you may notice a whirring or humming noise coming from the fuel tank area, toward the rear of the car. The lack of fuel may result in the engine operating without enough fuel relative to the amount of air, causing the check engine light to appear. Sometimes a fuel pump will fail slowly, and that means the fuel pressure and volume slowly degrades. A failed fuel pump may prevent a car from starting or stall it.
If it fails to produce adequate pressure or completely quits operating, it will need to be replaced. However, as with any electro-mechanical component, a fuel pump will eventually degrade and fail. When to consider replacing the fuel pump?Ī high quality, OEM fuel pump can last indefinitely.
