Higher viscosity fuel oil can make it harder for the fuel pump to pump the fuel through the system, leading to increased wear and potential damage to the pump. It can also affect the spray pattern and atomization of fuel in the injector, impacting combustion efficiency and engine performance. Lower viscosity fuel oil is generally preferred for better pump and injector performance in a diesel engine.
Fuel injector cleaner is a liquid which one puts in their gas tank to clean the engine and improve fuel performance. Fuel injector cleaner can be purchased at Canadian Tire, Walmart, and at many gas stations.
Depends on the make/model of your car and the desired performance of the injector, but generally in the area of $25 - $300 for the part.
A fuel level sensor will not affect performance. Fuel level can due to weight of fuel and accumulated heat in the returned fuel from the engine.

A 92 Chevy Caprice that has no injector pulse mostly likely has clogged injectors or a defective fuel pump. Fuel injectors must be cleaned periodically to removed buildup for peak performance.
The most likely problem is the fuel pump. When you turn the car's accessories on you should hear the fuel pump turn on. It shouldn't be very loud. If you don't hear, it may be broken. You should check it. If it is in good shape check the carb/injector. If the carb/injector isn't damaged its a fuel line problem.
Leaking fuel filter or fuel filter connections; Plugged, dirty or poorly connected fuel injector(s); Punctured or damaged fuel tank.
Fouled, damaged injectors or incorrect timing on fuel injector pump
Where is the fuel injector located?
Could be a combination of things. Plugged or damaged pcv valve; Loose or damaged oil drain plug; Worn or broken piston rings; Plugged, dirty or poorly connected fuel injector; Leaking fuel filter or fuel filter connections; Faulty fuel pump or connections; Punctured or damaged fuel tank.
The fuel injector provides the fuel. The spark plug provides the fire.
