So i been driving around with my one little mod of an air intake and a breather filter, then all of a sudden one day my car doesn't start. Eventually I get it started but some days I would have to turn the key like 15 times. At first I thought it was the alternator then the battery and even the starter. But after going to my local autoshop they told me everything was good. My car has 112,000 miles on it and i really dnt think any of that stuff should be acting up, given i take care of regular maintenance. My other car enthusiasts friends say its my fuel filter. The car isnt getting fuel so thats why its not starting right away. Just wondering if anyone else has ever had this problem or heard of this problem? Advice please
