2004 Pontiac Sunfire

Are you out of gas?

Does it crank or do you get nothing when turning the key?

Try spraying some carb cleaner or starting fluid into the throttle body and then crank it, better to have someone crank it while you spray some in. This will help
tell if this is a lack of fuel loss problem.

We need to check for lack of fuel, spark and or compression.

Take a look at the "first things to check" section of our site menu.
