WHY IS MY MERURY GRAND ONLY CRANKING BUT NOT STARTING ??

2003 Mercury Marquis • 150,000 miles

I just replaced fuel filter last week. And I can here my fuel pump turn on. My check engine light hasnt been on. It only does this sometimes not on a regular basis. (But has very bad timing when it does haha)

When it happens, you need to check if spark and fuel are getting to the engine. One will be missing. Let me know what you find.
