Q: Car not starting

asked by on December 29, 2016

My car is currently not starting and there was few things I suspected that could be it and after I changed them it still wouldn't start. I changed the idle air control valve, battery, and spark plugs and still no luck, which all of them had to be changed regardless. The car at least cranks fine. The previous owner told me she had to change the spark plugs every 3 months or so which is insane. So when I took out the spark plugs the end piece where it's supposed to spark was caked in gunk so a friend told me something inside the engine could be shot like maybe the pistons. What else could be the issue?

My car has 220000 miles.
My car has an automatic transmission.
