did you properly reprime the lines first ? if you replace the pump and filter you need to turn the key of and on at least 5 times before starting it for the first time. If this is not the case then start from the top and work your way down. Check for fuel in the cylinders by pulling a spark plug. if you can smell gas from the cyclinder there is fuel. Next check for spark from all the plugs. if you have spark that is fine. next check for vacum and air flow. some of the rubber plastic lines tend to break. Try that and then get back to us.
