Heres my problem. Car at times will not start, turns over nice but no fire. I hear the fuel pump kick in everytime I turn the key on. Next day car will start no problem, week later car will not start, try several minutes of turning car over it will fire and drive perfect. Very intermittent starting problem. car is sharp and fast but this starting issue is a pain . would like to sell it to get a Dodge truck but can't always count on car starting. 120,000 miles on it. Thanks for any help

 

Welcome to DF

My guess would be either crank or cam sensor. Do you have a check engine light on?

 

Yes ; First thank you for your help ! Guy at Auto Zone says its for an O2 sensor. Crank and cam sensors not very expensive so i will give it a shot. Thanks again
