If you're still unable to get your car to start, it's quite likely that you're dealing with a bad starter motor. Although you can permanently fix this issue by replacing or repairing the starter motor, you could use a hammer as a possible quick fix to at least get your car going. This is because the starter motor, over time, can develop certain dead spots between its armature and field coils. To close that gap and remove the dead spots, you can gently tap on the back of the starter motor with a hammer. Do so gently, and keep tapping 4 to 5 times (in quick succession, but lightly), usually by the rear, side, or top of the starter motor.
