Hello, thanks for writing in about your Chevrolet Malibu. If you have spark and fuel pressure then you may have a bad camshaft sensor. This sensor is responsible for telling the computer where the number one cylinder is. The fuel injection and spark timing needs this sensor to run correctly. If you need some help with fixing this, consider YourMechanic, as a certified technician can come to your home to properly diagnose your starting issue firsthand. Good luck.
