The tensioner could be bad, but that up to the guy who has it at his disposal to look at.

As for it not starting now, it may be getting expensive for you. The 2.5L is an interference engine. Meaning if the timing belt breaks or jumps teeth the valves may hit the pistons, resulting in bent valves. Bent valve can result in your symptoms to a tee.

when i try starting it there are loud pops from the throttle body and smoke coming out then it will crank but not start
The smoke and popping back through the intake could be the result of the cam timing being off, if your lucky. Otherwise it is the result of a intake valve being bent and not closing all the way. If it is the later, the minimum you are looking at is pulling the heads and installing new valves with a valve job. If there is significant damage to the piston from contacting the valve they should also be replaced.
