When the engine fails to start when hot and it's fuel related it's usually because the pressure drops below what it takes to open the mechanical injectors. That's caused by either a weak accumulator or a bad check valve in the fuel pump. At that point if you unplug the blue connector from the cold start valve and the gray plug from the warm up regulator and then plug the gray plug to the cold start valve you will fire the cold start valve during engine cranking. The cold start valve is actually an electric fuel injector and by firing it you introduce enough fuel to get the engine started. You should then immediately unplug the gray connector from the cold start valve and return it to the warm-up regulator. Plug the blue connector back on the cold start valve and think about getting the low fuel pressure problem fixed. This isn't a permanent fix, it's a limp home emergency procedure. Bruce Benson
