Question
my 2000 seville sls wont start. it says very low fuel and i just got gas. it says 0% oil life i just changed the oil five daty(220 miles ago) where should i look for the problem or how can i fix this.

Answer
FIRST you have to determine if your fault for not starting is because of NO fuel or NO spark to the spark plugs.

The very low fuel indicator is most likely a faulty sending unit in the gas tank.

The 0% oil life just needs to be reset. Look in your owners manual for how to reset it.
