No Water to Icemaker

I am trying to fix an icemaker on an old fridge that was given to a friend. There is no water to the icemaker. I installed a new water inlet valve. I have blown out the lines and there is still no water going to icemaker. There is water going to the water dispenser however it is very low pressure. This is on a well and the water pressure is not good normally. Could this be the problem. This lady has little money and I hate to keep replacing things without knowing it is going to work. Any advice?
