Thank you for answering back to my question about my 2000 buick regal. All our suggestions were good, but we found the real problem when the car did not start one morning. When I turned the key on, but not far enought to start the car I could not hear the fuel pump turn over as a pre pump. Laid down under the car and gave a couple hits close to where the fuel pump is. The car fired up, telling me that the pump had a dead spot. Got the car towed again to the shop, not a cheap fix, $450.00 for the pump, with the labor and GST, $893.00.
