2006 Buick Rendezvous Fuel Pump Reset: A Complete Step-by-Step Guide

The bottom line: If you own a 2006 Buick Rendezvous and you are dealing with hard starts, stalling, or an engine that cranks but refuses to fire after running low on fuel, the fuel pump reset is often the first fix to try. On the 2006 Rendezvous, the fuel pump shutoff switch is designed to cut power to the pump in the event of a collision, and it can also trip if the vehicle runs out of gas or experiences a sudden jolt. Resetting it is a quick, no-cost procedure that you can perform in your driveway with no special tools, and it restores fuel flow so the engine can start normally again. In most cases, the reset takes less than five minutes once you know where to look.

What Does the Fuel Pump Reset Actually Do?

The 2006 Buick Rendezvous is equipped with an inertia fuel shutoff switch, commonly called a fuel pump shutoff switch. This safety device is a standard feature on many General Motors vehicles from that era, and its job is simple: in the event of a collision, it cuts electrical power to the fuel pump to prevent fuel from being pumped in an accident situation. The switch uses a small internal mechanism that trips when it senses a sudden impact or deceleration.

However, this switch does not only trip in crashes. Several everyday situations can cause it to activate, which is why so many Rendezvous owners encounter a no-start condition without ever being in an accident. The most common triggers include running the tank completely dry, hitting a large pothole or curb, or even going through a rough railroad crossing. When the switch trips, the fuel pump stops receiving power, and the engine will crank over but never fire up.

When you "reset" the fuel pump, you are simply pushing the reset button on this switch to restore power to the pump. It is important to understand that this is not a computer reset, and it does not involve clearing diagnostic trouble codes. It is purely a mechanical re-arming of a circuit breaker style safety switch.

Where Is the Fuel Pump Reset Switch on a 2006 Buick Rendezvous?

Before you can reset anything, you have to find the switch. On the 2006 Buick Rendezvous, the fuel pump shutoff switch is located in the passenger compartment, not under the hood. Specifically, you will find it on the passenger side of the vehicle, behind the kick panel on the right side of the center console area. In some trims, it may be tucked behind a small access panel or plastic cover that you can pop off with your fingers or a flathead screwdriver.

To make this easier to visualize, here is what you should do:

  1. Sit in the passenger seat and look at the area near your right foot, against the center console.
  2. Feel for a small rectangular plastic cover, roughly the size of a credit card, that pops off.
  3. Behind that cover, you will see a round or rectangular switch with a small red or black button, often with a rubber boot over it.

If you cannot find it behind the kick panel, check the owner's manual under the "Fuses and Circuit Breakers" section. The manual for the 2006 Rendezvous specifies the exact location, and it is always wise to confirm before you start pulling panels off.

How to Reset the Fuel Pump: 6 Simple Steps

Now that you know where the switch is, here is the exact procedure to reset the fuel pump on your 2006 Buick Rendezvous. Follow these steps in order, and do not skip ahead.

Step 1: Turn the ignition to the OFF position. Make sure the key is completely out of the ignition or turned to the accessory off position. You do not want any electrical load on the system while you work.

Step 2: Locate the fuel pump shutoff switch. As described above, it is behind the passenger side kick panel or center console cover. If you have a manual, double check the diagram for your specific trim level, since some Rendezvous models have the switch in slightly different spots depending on options like rear climate control.

Step 3: Remove the cover. Use your fingers to pop the plastic cover off. If it is tight, use a trim tool or a flathead screwdriver wrapped in tape to avoid scratching the panel. Set the cover aside.

Step 4: Press the reset button. You will see a button on the switch. Press it firmly until you feel a click. The button may be recessed, in which case you will need to use a screwdriver handle or a pen to push it down. Hold it for one full second, then release.

Step 5: Reinstall the cover. Snap the plastic cover back into place. Make sure it is seated firmly so it does not rattle or fall off while driving.

Step 6: Test the vehicle. Get in the driver seat, turn the key to the ON position, and listen for the fuel pump prime. You should hear a faint whirring sound from the rear of the vehicle for about two seconds. After that, crank the engine. It should start normally. If it does not start, press the reset button again, and also check the fuel pump relay and fuse, which are covered below.

When Should You Reset the Fuel Pump?

You do not need to reset the fuel pump as part of regular maintenance. The reset is only necessary when the shutoff switch has been tripped. Here are the most common scenarios where a reset is needed:

Running out of fuel. If you let the tank run dry, the sudden change in fuel pressure can sometimes trip the switch, especially if the vehicle sputtered and jerked as it ran out. This is one of the most frequent causes of a tripped switch on older GM vehicles.

A minor collision or bump. Even a low speed bump in a parking lot can be enough to trip the inertia switch. It is designed to be sensitive, so do not assume you need a major accident for it to activate.

Hitting a large pothole or curb. A hard jolt from the road can occasionally trip the switch, particularly if the vehicle is older and the switch mechanism has become more sensitive over time.

After a fuel pump replacement. If a mechanic has recently replaced the fuel pump, the switch may have been tripped during the work, or the pump may need to be primed. In this case, resetting the switch is part of the standard post repair procedure.

What If the Reset Does Not Fix the Problem?

If you have pressed the reset button, heard the click, and the vehicle still will not start, the problem may not be a tripped switch. Do not assume the worst, but do work through these checks in order.

Check the fuel pump relay. The relay is located in the underhood fuse block. On the 2006 Rendezvous, it is typically labeled "FUEL PUMP" or "FP." Pull the relay and inspect it for signs of burning or melting. You can also swap it with an identical relay from another circuit, like the horn or the wipers, to see if the pump starts working.

Check the fuel pump fuse. Look for a fuse labeled "FUEL PUMP" in the underhood fuse block. If it is blown, replace it with a fuse of the same amperage. If it blows again immediately, you have a short in the wiring or a failing pump motor.

Listen for the pump prime. When you turn the key to the ON position, you should hear the pump run for about two seconds. If you hear nothing, the pump is not receiving power or the pump itself is dead.

Check for diagnostic trouble codes. If your check engine light is on, have the codes read at an auto parts store. A code like P0087 (fuel rail pressure too low) or P0231 (fuel pump secondary circuit low) points directly to a fuel delivery issue.

If all of these checks pass and the vehicle still will not start, the fuel pump itself may have failed. On a 2006 Rendezvous with over 150,000 miles, pump failure is not uncommon, and you may be looking at a replacement rather than a reset.

Fuel Pump Reset vs. Fuel Pump Replacement: What Is the Difference?

Many drivers confuse the reset process with replacing the pump, so it is worth clarifying. The reset is free, takes five minutes, and is the first thing to try when the switch has tripped. It does not repair a worn out pump and it does not fix low fuel pressure caused by a clogged fuel filter.

A fuel pump replacement is a significant repair. On the 2006 Rendezvous, the fuel pump is part of the fuel pump module assembly, which also includes the fuel level sensor and the fuel strainer. The entire module sits inside the fuel tank and must be accessed through an access panel under the rear seat. This job requires dropping the tank or cutting an access hole in the floor pan if one does not already exist.

If the reset does not solve the issue and the relay and fuse check out, you should have the fuel pressure tested before ordering any parts. A fuel pressure gauge connected to the fuel rail test port will tell you if the pump is delivering the correct pressure. The 2006 Rendezvous should have around 50 to 60 psi with the key on and engine off.

Preventing Future Fuel Pump Problems

A reset is a quick fix, but you can take steps to avoid needing it in the first place. Here are practical habits that reduce the chances of the shutoff switch tripping or the pump failing prematurely.

Keep the tank at least a quarter full. Running the tank low regularly does more than trip the switch. It also causes the fuel pump to run hotter, since the pump is cooled by the fuel that surrounds it. Low fuel levels shorten pump life significantly.

Replace the fuel filter on schedule. A clogged fuel filter makes the pump work harder, increasing current draw and heat. On the Rendezvous, the fuel filter is an inline unit located under the vehicle near the fuel tank. GM recommends replacement every 30,000 miles.

Drive carefully over rough roads. While you cannot avoid every pothole, being aware of the inertia switch and its sensitivity can save you a no-start situation. If you do hit a large bump and the engine dies, check the reset switch first before calling a tow truck.
