One pull the negative battery post off the battery for 30 second’s. This clears the computer codes and the light. However it also clears your radio presets and clock. Another way is to pull the fuse labeled “Fuel Pump”. This fuse is in a box under the hood behind the battery (See photo to the left), Should be the only yellow 20AMP fuse in there.
