The engine has been rebuilt with the majority being new parts the block and head are not. They have tried numerous times to set the timing using a new belt and also replacing the tensioner. When attempting to start it the timing jumps the vehicle won't turn over like a low battery which is brand new. If you could give me any advice I would thank you so much.

was a timing belt kit installed which would include the idler pulley if not thatmay be why it's jumping or the belt wasn't properly installed.Ensure timing marks are still aligned. Install timing belt in a counterclockwise direction starting at the crankshaft. If reusing old belt, ensure it is installed in original direction of rotation. Keep belt span between crankshaft and camshaft tight while installing timing belt over camshaft.
Remove drill bit and tighten tensioner bolt. Rotate crankshaft clockwise 2 revolutions. Recheck timing mark alignment. To complete installation, reverse removal procedure.
also check compression your valves may be bent. then check crank sensor that is usual cause of a no start
