Hello. If the scan tool will not connect with the computer, then this is the first sign that there may be a computer issue. I typically start by testing the power supply to the computer and the ground. If it has both and is not turning on then there is a computer failure. Most of the time though this is caused by a voltage problem. From my experience with this vehicle, this is usually caused by a failure in the ignition switch. When it fails it stops providing power to the necessary circuits to turn the computer on. I usually test this first. It can also be a failure in the fuse box but that is not as common. If you need to have this crank no start looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the starting problem and guide you with repairs.
