When replacing the battery I accidently touched my wrench from the positive terminal to bare metal which caused my fuel gauge needle to go completely around to the stop pin. Had to use the trip mileage for the last 5 years to gage when to fill the tank. Found out on this site that a magnet placed against the plastic directly in front of the needle and rotating it counterclockwise would put the needle back in position. Did this and now works fi...
I've had an intermittent no-start condition on my 2000 Buick Park Ave. This started happening on occasion and was nerve racking. Took it to my local mechanic shop and he replaced the crankshaft position sensor which solved the problem. Found the problem with the sensor 'A'(18X24X) out of range. Code PO336-CKP. in the computer. Hope this info will help others who have this problem.

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost.

Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.
Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
