Why won't my 2009 Dodge Caliber start, even after installing a new battery and verifying that the vehicle's grounds are in good condition, and what can I do to resolve this issue since I cannot fix it on my own?

If you've installed a new battery and verified that the grounds in your 2009 Dodge Caliber are in good condition, but the vehicle still won't start, there may be several potential reasons: Faulty Starter - A faulty starter can prevent the engine from turning over, even if the battery is in good condition. Ignition Switch Issues - A problem with the ignition switch can prevent the starter from receiving the signal to turn the engine over. Fuel Delivery Problems - If the fuel pump or fuel injectors are not functioning properly, the engine may not start. Electrical Issues - Electrical problems, such as a blown fuse or malfunctioning computer, can also cause starting issues. Unfortunately, these issues are often difficult to diagnose and repair on your own. It's best to take your vehicle to a trusted mechanic who can properly diagnose the issue and recommend the appropriate repairs. Possible solutions may include repairing or replacing the starter, ignition switch, fuel pump, or fuel injectors or addressing any electrical issues.
