What’s else can I check?
I was driving my car and it shut off. Now all it does
is crank but won’t start. I changed the fuel filter and
checked the fuel pump. I also cleaned all the
battery connections. But still won’t start
The best thing you can do is go to a car parts store and borrow an OBD code reader. Find the codes and address those problems. There are so many things that can cause an engine not to start that you could be guessing for months before you actually find it. If you're not confident in your diagnostic skills, do what most people do: tow the car to a mechanic and have it fixed properly.
