1983 944 no start, humidity related


Vehicle Information: Model(924/944): 944; Year: 1983; Engine (type, size, modifications): Stock; Total Mileage: 120,000;

Engine will start very well when kept in dry, slightly heated shop. Engine will not start, or fires but will not run, when kept in enclosed, unheated and occasionally moist concrete-floored shed. After no-start in the shed about a week in the shop with the hood up cures the problem. Have cleaned all grounds on vehicle, changed DMEs (I have a serviceable spare) and verified fuel pump operation. Battery and starter are like new.
