Car won't start
Asked by Katora Mar 27, 2019 at 12:10 PM about the 2002 Nissan Sentra
Question type: Maintenance & Repair
My 2002 Nissan sentra won't start. It turns over
and cranks but just won't start. The battery and
alternator are fine. We changed a few fuses but
still having problems. We are pretty sure it's a
electrical issues but can't figure it out.

Check for spark ,fuel and fuel pressure if all are present possible timing and or cam or crank sensor the sensors can be tested with an ohm meter also remove o2 sensor for the possibility of a catalytic issue

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.
