i have a 2002 toyota sequioa and i just recently installed a new lock cylinder
but now when i try to start it, the engine cranks but doesnt start. The battery is

If you replaced the lock cylinder with a new key, the issue is the key and lock need to be programmed aka flashed to the vehicle to start it. It's all part of the anti theft system. A locksmith, mechanic or dealer can help you.
