GP40-2 start engine issues

[Roadmaster259]

I bought the GP40-2 Loco Pack Add-on and I can't figure out how to start the locomotive in the scenario "[GP40] 02. D&RGW "Railblazer."

I pressed "Z", I used the green key in the HUD. Nothing! Do I have to prime a fuel pump, or something? Is there a switch that must be engaged before I can start up the engine?

Make sure Engine Control and Fuel Pump are turned on and the isolation switch is set to Start/Stop. Then press the start button, after the engine is started, flip up the Gen Field and you'll be good to go.

On the main panel turn on these switches, Engine Run, Gen Field, and Control and Fuel Pressure. On the back overhead panel turn the Isolation Switch to the Start-Stop Run Position then press the start button. The F4 Hud start button doesn't function for this loco or even the headlight button everything has to be done from the cab.

Many thanks for your assistance, gentlemen. I found it necessary to flip the isolation switch back to its original position in order to get the loco to move when in gear. I'm off to the races, now!
