I changed the crank sensor the timing belt and the crank sprocket

It sounds like you possibly have the timing of the engine incorrectly set. If you would be willing to bring the vehicle to our shop, I could have my ASE Master Certified technician diagnose your vehicle to determine the exact cause of your vehicle not starting. Give us a call at 773-725-9414 and we can further explain how we can help you.

Did the old timing belt break? .. 'IF' belt 'breakage' was the reason you "changed" the components you mentioned, (Google > interference engine)... The 3.5L is indeed an interference engine, IF the timing belt brakes or the engine is rotated while out of time, valve to piston contact may occur resulting in internal engine damage .. In any event, further hands-on testing & diagnosis is needed .. Good luck with it!
