Car has been jerking for almost two years. Mechanic said it was coils, replaced all of them but the car was still jerking. Our Mechanic doesn't seem to know what is causing this. We realized for some reason when the fuel tank is full the car doesn't jerk but when it is half full the jerking starts again. What is causing this and how can we fix the jerking?

This happens when the fuel pump gets weak and needs replacement. here is how the job is done in the images below. You will need to remove the rear seat. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
