Hello, my name is Bobby. Can you tell me if the engine is cranking over fine and just not starting? Did the vehicle die while driving or just refuse to start all of a sudden?

Customer: replied 1 year ago.
The starter died. Replaced starter and battery. Was not on the road. Parked.

correct. check engine light says oxygen sensor is not working. (using meter.)
Expert:  FIXITMAN replied 1 year ago.

Thank you. When you turn the key on listen to see if you get a humming from the fuel tank. If not then the fuel pump may be bad. If it comes on then you need to determine if the engine is lacking spark or fuel. You can add some fuel directly into the engine where the hose from the air filter connects. If the engine starts then it is fuel related. If not then it may be spark. It may be a fuel injection unit failure or a bad crank sensor.
