When I crank my car, it will not stay crank, and when it crank up it runs rough, so what's my problem with it?

Engine running rough or misfiring can be cause by the following:

1.Defective spark plug
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.

8.EGR valve that is leaking.
9.Oxygen sensors.
