The Buick Regal is a midsize sedan that initially ended its production run in 2004, but was brought back to the North American market beginning with the 2011 model year. The 2000 Regal represents the fourth generation of manufacturing for the automobile, and features a 3.8L V6 engine and a four-speed automatic transmission. Problems with the fuel delivery or ignition systems may prevent the Buick Regal from starting properly.
If the Buick Regal Won't Crank
Perform a jump start on the Regal using another functioning vehicle and jumper cables.2
Allow the Regal's engine to idle for several minutes if jump-starting the vehicle is successful. This will allow the battery to charge up.3
Shut down the Regal and remove the jumper cables after several minutes, then attempt to start the vehicle again. If the Regal still doesn't start, the battery is failing to hold a charge and will need to be replaced with a new battery.
If the Buick Regal Cranks
Ensure that there is gas in the fuel tank. Running out of gas is a common reason that a Regal will crank without starting.5
Ensure that each spark plug has a clean connection without any corrosion.6
Remove the timing belt cover. Inspect the timing belt to ensure that it is intact. If the timing belt has snapped, replacing it is a very involved and complicated process and it may be necessary to consult a qualified mechanic.7
Turn the key to the "ON" position and listen for the fuel pump to pressurize the injection system. If you hear nothing, the fuel pump may need to be replaced.
