Yes, check for obstructions. However, also check to ensure that you used an OEM pressure switch! See this video for an explanation: Amazon Furnace Parts: http://www.amazon.com/s/?_encoding=UTF8&camp=1789&creative=390957&field-keywords=gas%20furnace%20parts&linkCode=ur2&tag=amznelite-20
This is a air proving problem. You need to check your flue for obstructions like birds nests, rodents, snow, ice, etc. The inducer motor creates a draft that is proved by the pressure switch. This will not make if there is a restriction somewhere.
