It sounds more like a loose engine or sump cover which some cars have tokeep dirt off various parts. sometime they come loose thru missing screws and the wind catches them as u go and makes them flap about, but as u go fast the wind force pins them back so they dont flap

What are the symptoms of a broken time chain on a 2006 4 cylinder Toyota tacoma

Strange things happen when a timing chain breaks. This chain drives the camshaft at exactly half the speed of the crankshaft. If the chain breaks it could jam the crankshaft so that the engine can't turn, even by hand. If the engine does turn and the chain is broken, you will hear an uneven cranking sound coming from the engine.
What usually happens is that one or two cylinders end up with all valves closed, and this causes a high compression as the engine is turned by the starter. The valves on the other cylinders remain open all the time and there will be no compression on these., so the engine sounds as if it is turning fast, then slow in very quick succession.
It often happens that, because the timing is out for the short while that the engine turns without the timing chain, the valve timing is out by so much that the pistons strike the valves and bend them, so that there is no compression whatsoever, and when you crank the engine with the starter, the engine just spins freely. In any case, whatever the symptoms, the engine will not start!

My engine died after replacing water pump there was a flapping sound then it died and would not start.

Unfortunately, it sounds like the timing chain has broken,(the "flapping sound"), did you check for spark or use a timing light. If not I would start there. Cost nothing and will rule out a costly repair. Or will confirm my hunch

Noise from engine front end

it is always good practice to replace idler pulleys , seals , hydraulic adjuster when replacing a timing belt as the everything is worn out as well
It is now possible that the idler bearings for the belt are failing
If the pulleys , crank and cam seals and hydraulic adjuster were all not replaced with the belt then they job will have to be done soon

Hear sawing noise under the car in sink with wheel rotation

Sounds like you have a bad CV (constant velosity joint) This also may be the sound of a bad wheel bearing. If the vehicle has 75,000 miles or more this may be highly likely. You also may need a brake job. The sound you are describing sounds like it could be brakes grinding metal on metal.

Does the water pump have to be replaced with the timing belt?

teh resaon he wants to replace your water pump is because it runs off of your timing belt.and if it should fail later down the road after belt replacement.then you will be looking at another big expense having the same job done twice.i would rcomend you do get the waterpump replaced for you other problem im not sure. samboiv
