98 Malibu hard starting

my 98 mailbu with 96000 km with the 2.4l engine is having problems starting. Sometimes it starts right up and other times it crancks and crancks and crancks with no start. This problem started a few days ago. All lights come on and when it starts car runs good as it always did. I changed the plugs as a start but problem is still there. Any help would be appreciated? Thanks.

SOunds like ignition coils.
