06 impala won't start

Hello, sounds like a voltage drop of some kind - ensure the battery is fully powered and able to sustain a load. If it is, then check the battery cables - are they fully secure and clean of all corrosion? If so, then you'll want to check to see if the starter motor is drawing too much power. Hands on testing is needed. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
