Dont laugh when i ask this but I seen it happen before, Is there gas in the tank?
Its at the rear of the engine in the intake manifold. Take the 2 bolts off that hold it and clean all of the carbon before installing the new one.
The 1997 Buick LeSabre intake manifold bolt torque specifications is 45 pounds per square inch. The manifold bolts should be torqued in 15 pound intervals.
You must remove the fuel tank in order to access the pump. Once you have the tank out, it is just a matter of removing the pump and installing the new one.
Manifold Absolute Pressure/Barometric Pressure Sensor
The Coolant Temperature Sensor on a 1993 & 1994 Buick LeSabre is located on driver's side of the car under the throttle body, It is screwed into the lower intake manifold. You cannot see it without first removing the throttle body since it is hidden under it. An electronic plug is clipped to the the end of the CTS.
replace the water heater inlet pipe on the intake manifold on a 3800
Manifold ait temperature sensor circuit. Year and model?
Hook it to a battery charger.
Exactly the same except the Lucerne has the improved metal manifold pipe. I think the 04 and 05 LeSabre also replaced the plastic pipe with metal.
The IAT sensor is located on the intake manifold air cleaning housing or air duct.
Most likely a cracked intake manifold.
Struts on a 1998 Buick LeSabre are changed by jacking the vehicle up, removing the wheel, and unbolting the strut. It can then be pulled from its mounts and a new strut put in place.
