Car won’t start and I changed my starter and the alternator and I have power in the batter and have power in the car it’s just make a clicking sound when I try to turn the car on

Hello, if you insist that your battery is fully charged and able to accept a load, and you can verify that the starter motor is going to turn properly when engaged with proper power, and you can ensure all the cables are secure, free of any corrosion and any damage, then I would be concerned that your engine may be locked up. If your engine is seized, the starter motor will not be able to turn it. The best way to find out is to have someone put a breaker bar and socket on the crankshaft and try to manually turn it.
