car not starting

The car was not having power, driving very slow, we parked it, for 2 months. we replaced spark plugs. after we replaced the plugs the car could not start, it was cranking.when we try to diagnose the problem it fault of camshaft sensor A, and inter-cooler hose. We replaced the camshaft sensor the car still not starting.we took out the battery and recharged it and put back, the car is still not starting. Please advice as to what could still be the problem. Thank you. Regards, Olivia
