Because the timing chain is a mechanical component of the engine that synchronizes the top of the engine (valves, lifters, dist etc...) with the bottom half of the engine (crank, pistons, etc...)
If the timing chain were stretched and/or the gears worn it may have skipped a tooth or two. However, you'd still have spark. Albeit at the wrong times and erratic, but there's still be spark.
No the ECM shouldn't make any high pitched whines.
