Ok you have a broken item. In your mind you go through the operation and the processes needed for this item to function. These days almost all components have electronics and because these are difficult at times to troubleshoot the first order is to replace them until the item is fixed.
Unfortunately during your research if your reading internet posts in general the results skip over the very basic steps of troubleshooting. Do the mechanical connections and a very good visual inspection. In my professional routine I would do a lot of grabbing, pulling and twisting. Look for obvious visual clues.
Example: I Love Diesel Engines and especially the 5.9 Cummins in my truck. On my morning routine I fired it up, but was left with no acceleration. Dead pedal is a common reference term. The truck runs, goes into drive but won’t increase RPM when depressing the accelerator
This is where the lesson comes in. Researching at the beginning referred to the Throttle Position Sensor TPS. Why, because it’s electronic and a simple change out. Before purchasing this component (80 bucks) I went through my memory and theory of my 5.9’s ability to operate without any electronics, say after china detonates an EMP, or for folks like me who believe 9-11 was an inside job, the NWO does it and eliminates electronic capabilities. (I couldn’t resist)
The Point: Alot of online pro’s give bad advise because thety are not there to do a visual inspection. The information you give can’t be detailed enough to get to the right conclusion.
My truck can run without a TPS, it’s purpose is to present information for computer decisions but not to control the fuel distributer. The system is mechnical. Check the mechnical links!
Visual inspecting reveled the rod the fuel control link had the connecting end fail and fall off.
