we were driving the car and it died, it would start then stall, after it was towed home, it wont crank. when you turn the key, you hear the starter engage, but it will not crank the motor. Starter has been replaced along with the relay, grounds seem good.

Manually crank the engine to check if it has seized.

Ensure the battery is good, Try a jump start. You might have a failed alternator instead of a starer.

The motor tried to Crank once, since then it will not crank. Battery is good and a jump start does the same thing.

Check to see if the engine is seized. It could also be due to a bad idler bearing or compressor. If the engine seems seized, remove the accessory beltings and retry.
