A dealership recently cleaned my fuel injectors and did a pcm update. After getting the car back I noticed that when I turned the engine on I heard 3 or 4 knock sounds from the back of the car as the engine started. A friend said it might be the fuel pump. It stopped and the car seemed to start without making any unusual sounds and a couple of weeks have gone by. The noise reappeared reappeared once today and stopped. Does anyone know the cause/cure?
