1979 924 Hot Start Problems


Vehicle Information: Model(924/944): 924; Year: 1979; Engine (type, size, modifications): 2.0; Total Mileage: ?;

My 79 924 starts cold and runs great. If it sits 1-3 hours, it is hard to start. It will crank for 1 minute before starts. It will initially fire and than immediately die first. I pulled the spark plug after 30 seconds of hot cranking and it was dry. No fuel vapors came out of the spark plug hole while cranking. Is it the cold start valve,thermo time switch, electric solenoid,control pressure regulator,or something else? The fuel pump is running and fuel sprayed when I loosened the fuel line on the fuel dist.
