Metroliner
I flew about 1,100 hours in Metroliner III aircraft in 1993 - 1994 which were equipped with Garrett TPE-331-11U engines. These engines were rated at 1,000 HP dry and 1,100 HP wet. They gave the Metro a TAS (for flight planning purposes) of 280 KTAS.
Starting was a very simply affair. There are 2 push-buttons on the skirt panel located slightly to the right of the left control column, one each for each engine.
You pushed the button and the engine began to spin up. At some point (I'd have to look at my old ops manual) the ignitor would light and the fuel would begin to flow. I recall this being around 20 - 30% RPM but could be wrong as it has been 16+ years. You could hear the fuel ignite and the RPMs would really begin to pick up. You would monitor the temperature gauge as the temp could go up to 770 degrees C but for only a few seconds. It should settle down below (again if I recall correctly) 650 degrees C. This number was based on the SRL (Single Red Line) computer being operational. Of course there was also an oil pressure gauge for each engine. If the start "hung" for any reason, there was a stop button just below the start button which shut off the fuel to that engine hence aborting the start process.
Also, after the engines were started you had to briefly pull each power lever over the gate to reverse the prop. This released the prop from the stops. These stops were mechanical devices which kept the prop from going into feather when the engine was shut down. As the TPE-331 engine is a single shaft turbine, the prop can not be in full feather or it will cause too much drag on start up which will overtemp the engine. If the shutdown was not done properly, there is a switch on the left side panel which will cause a pump to force oil into the prop hub thereby pushing the prop out of feather and back on to the stops.
On the center panel between the pilots and just below the power levers are 2 large red knobs. These are the "stop and feather" controls. They mechanically shut off the fuel, stopping the engine and cause the prop to go to feather. They are used in-flight if you have and emergency and need to shut down an engine.
I hope this helps!
