If your car doesn't start but the dashboard lights flash, it's typically a sign of a weak battery or a poor connection between the battery and the starter. Start by checking the battery terminals for corrosion or looseness, and clean or tighten as needed. If the problem persists, testing the battery's voltage with a multimeter can confirm if it needs to be charged or replaced. It's also wise to inspect the starter and electrical connections for any visible damage or wear.
