Not starting

Probably your starter getting ready to go out. Before the starter goes out it tends to let you get one or two more cranks in before getting stuck. Locate your starter and tap on it fairly hard and quick with whatever you can reach it with. Tap on the big part of the starter NOT the little part where the wires are connected while someone is cranking the key to try and start it. Do this about 4 times if it doesn't start up you need to replace the starter where it sits or have it toed to a shop. Unless it's a Manuel then you can bump start it.
