intermediate cranking 1999 CL 3.0

HI my car is not intermediately cranking, i changed the battery I thought that would be the issue because it sounded like a dead battery noise, it would just
not even crank. I don't know if it's the ignition unit inside of the distributor cap but I turn the ignition switch and move it to neutral and sometime it turns on and sometimes it doesn't.


Any suggestions will be very helpful.
thanks
