Well ideally you want to crank the engine with the fuel pump fuse removed to prime the engine before starting anyways.
You may want to inspect the pick up tube in the oil sump for starters to make sure it's not all blocked up
as this could prevent you from getting a good prime and also could be the reason the timing chain fault occurred in the first place due to inadequate oil volume.
