My HD10 has begun to stall after a cold start....two years old. It runs for a time...poorly...and then stumbles and stalls. Waiting for a few seconds before turning the key to the start position doesn't seem to eliminate the problem. I think that I can hear the fuel pump running before turning the key to start position. I manage to get engine running by repetitive start attempts with "light pumping" of the throttle pedal. After the first stalls and stumbles, engine starts flawlessly throughout the day. Do have a problem at times in PARK....no crank/no start. If I move the shift lever to NEUTRAL...engine cranks/starts. Bad sensor at PARK position ?? Also notice a high pitch whine when turning off the engine. It persists for perhaps a minute and then stops. A high-voltage capacitor somewhere ??
Any ideas greatly appreciated ! May soon buy a new fuel pump and hope that it fixes the problem.
