The car will start and run every time you turn the key, but will only run for just a few seconds and then shut off.

Answer 1

Hi there,

If there is a problem with the cam position sensor the car will not want to stay running. This is how the engine knows it's in time. If it loses signal, then it will turn off. This could also be an indication that the timing is off.
