Not that I am aware of. Some imports provide an access plate under the back seat, but not American built vehicles.

I believe that I can help you.

Go to your throttle body.

  • A large diameter fuel rail is attached to the top of the intake manifold and supplies fuel to all of the injectors.
  • A fuel pressure cap is located on the rail for quick pressure checks,
  • The electric fuel pump is attached to the fuel sender assembly in the fuel tank. It pumps fuel constantly from the tank, through the fuel rail on to the engine and back to the tank.
  • The fuel pressure regulator that is mounted on the fuel rail maintains pressure across the injectors under all operating conditions.
Unfortunately, my scanner is inoperative and I cannot provide you with a diagram

SOURCE: How do I repair a broken fuel gauge in 1997 Buick

if your talking about the unit in the tank and not the dash unit then you will have to drop the tank and remove the unit from the can buy just the sending unit portion of the unit and not have to buy the entire pump unit with it.however if this is the original pump assembly then i would recommend that you replace the entire unit as it will more than likely need replacing shortly after repairing this problem.check to make sure its not a bad wire connection problem.

Location of fuel pressure sensor on a Buick lesaber 1999

If your talking about fuel tank pressure sensor, it's in the gas tank. My info says you need to drop the gas tank. You would need to drain gas tank before you drop it. Take electrical connectors loose. Take fuel lines loose. Make sure no pressure on the system before taking any fuel lines loose. So on and so on.

Where is the gas cap sensor in the 1998 buick lesabre?

If your problem is pressure when you release the gas cap it could be one of several problems. The first two are easy. A fuel pressure sensor on top of the charcoal canister under the computer and air filter on thew drivers side engine compartment. The next is the purge valve located on the front top of the engine under the cover. A hard line runs from the purge valve to the sensor on the charcoal canister.

The third is the most difficult. It is the fuel tank pressure sensor on top of the fuel tank. I believe you will need to drop or at least lower the fuel tank. Not an easy task. I have heard some models have an access plate in the trunk under the mat but mine did not. All are under $50.00 ea. and readily available at your local parts store or online. It is very important you get this fixed asap as it will build enough pressure to find a weak spot in the tank and rupture it. That happened to me.

While it is not ideal, you can temporarily loosen the gas cap to where it is just sitting in the filler tube when driving until you can fix it. Then have your check engine light reset.

Where is the fuel pressure sensor located on a 2002 GMC Sierra 1500 4X4?

The fuel tank pressure sensor on a 1999 GMC Sierra is located on the top of the fuel tank on the fuel pump itself. Most say that you need to drop the fuel tank to replace it but if you have access to a lift you can replace it without removing the fuel tank. By removing the rear U joint straps and moving the driveshaft to the side you can see and access the sensor for replacement. Chock wheels to prevent movement of the vehicle after driveshaft is disconnected.
