Welcome to Allpar. Auto parts stores can't diagnose and it is wrong for them to sell you electrical parts that can't be returned because it 'might' be this or that. Coil packs are generally reliable. You need to figure out what the vehicle needs and replace that.
Do you have 12 volts in at the center of the 3 wires at the coil pack? Do you have fuel pressure?
Do you have access to a good scan tool that can watch the crank sensor signal while the engine is cranking? Any history on the vehicle?
