Angry Problem with me Rheem 90 Plus

My Rheem 90 Plus furnace won't fire up i have no pilot light.
There are 2 green LEDS on the board lid up. The furnace blower motor is running and after 3 min the Big Blower kicks in but no heat. I cleaned the Furnace all out and new filter. The Model# is RCBA37656617. My question is why don't i get a pilot light. (Gas is on) Please help me Thank you so much. Randy

Ok i got the furnace working but it makes a pumping noise when the top cover is on and the cover moves in and out. When i take the cover off it works fine. What is the problem. Thank you Randy

Without being able to see & hear what's going on, I would only be guessing but it sounds like something is wrong with the air/gas mixture when the cover is on. For something like that a trained professional should take a look at the furnace.

The piping for the intake and exhaust might be too small. I think it needs to be 3" if its a far run to the outside.
