doesn't starts at all. Earlier had awful idling had to
turn ac off.had a couple stalling at stop signs few
weeks ago but went back on well. It's 316000miles
no check engine ever. What could be the problem.
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.
