Why will my engine not turn over after I replaced timing chain on a Chevy S10 202 liter
SOURCE: timing chain wear
That is correct. If your engine is whinning at about 2000 rpm's and its a high pitch whine, you need upper timing chains and chain tensioners. aka plastic gizmo as you called it. The timing chains ride off the plastic portion of the tensioner causing the noise, basically the chain is riding on steal stub from within the tensioner, that's where the noise is coming from. Waranree on this is 5years or 60000 miles which ever comes first. And the new tensioners are updated parts.

There are 4 small coild on the top of the motor, these are the ignition coils, 1 per spark plug. You have to pull the coils and the spark plugs are under them.

I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time.
Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".
If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.
Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common.
These chains are not generally expensive but replacing them can involve a fair amount of work.
Good Luck and hope this helps, Others will have different ideas.

there is a large evaporative leak. keep away form ottozoo, they dont have the brain power to actually diagnose a light bulb., their job is to sell parts., if they sell you the wrong parts tough.Take it to a qualified repair shop that does a lot of GM work or the dealer.

Hi, I have pasted the procedure below. Your spec is 0 degrees (right at TDC).
CHECKING AND ADJUSTMENT
HEI Systems
Do not pierce the plug wire insulation with HEI; it will cause a miss. The best method is an inductive pickup timing light.
The tachometer connects to the TACH terminal on the distributor and to a ground on models with a carburetor. On models with fuel injection, the tachometer connects to the TACH terminal on the ignition coil. Some tachometers must connect to the TACH terminal and to the positive battery terminal. Some tachometers won't work with HEI.
WARNING
Never ground the HEI TACH terminal; serious system damage will result.
TDC or Top Dead Center corresponds to 0°B, or BTDC, or Before Top Dead Center may be shown as BEFORE. A, or ATDC, or After Top Dead Center may be shown as AFTER.
