No.
A loose timing chain can cause the 305 h to jump time. with improper time, the engine will not start.
Chain is not timed correctly.
One way to tell if the timing chain is broken on your Nissan Altima is to see if it will start. If it starts, it is not the timing chain. You can also remove the distributor cap, have someone step on the gas while you watch the engine. If the rotor moves, it is not the timing chain.
check timing. timing advance. or slack in timing chain/belt
Yes, a broken chain or chain that is worn so bad it has jumped a tooth or 2 can cause the vehicle not to start.
