Why won't my car start with a new starter, new battery, and new relays?

Have you checked battery cables - are they clean, secure and free of corrosion? If it's a "click" only, under the hood from the starter, it sounds like a voltage drop. Have the battery checked as well to ensure it is fully charged and able to sustain al load. Last, have you ensured the engine actually turns manually? If the engine is seized, it will not turn. www.repairpal.com/repair-shops
