Check fuel pump and fuel filter.
My 2000 Express 1500 with 5.7 had same symptom at 110K miles. Fuel Pump was weak. Be careful putting fuel or starting fluid in throttlebody, it can flame back out at you and may damage the honeycomb MAF and it's expensive.
Yes it had a throttle body to control the amount of air getting into the engine.
it stops you from getting to many r.p.ms turning your engine and over heating it.
It would depend on what the problem is. All throttle problems can lead to a non running engine.
Either it is defective or not getting the right input from the engine control module.
One thing I have done is check the spring on the throttle. I had this happen and the spring that holds the throttle in a specific location had come unhooked. I simply held the throttle open, had another person sstart the mower and then reattached the spring to hold the throttle open in the desired position.
It is located on the throttle body, on the engine. It reads how far the throttle plate is opened.
A throttle is the system by which the flow of a fluid is managed by constriction. A throttle is used to monitor the position of the throttle in an internal combustion engine.
The throttle controls the governor which regulates engine speed.
There is no adjustment on the throttle cable.
Look in the engine compartment from the drivers side , you will see the big rubber engine air intake tube connecting to the throttle body at the top / front of the engine . The throttle position sensor is on the drivers side of the throttle body
Follow the big engine air intake tube from your engine air filter to the engine throttle body
Gas engine, on the throttle body. Diesel engine, on the injection pump.
