I have a heil furnace I believe my inducer motor don't have enough suction to open they pressure switch to allow the furnace to run , I token they line off and have sucked on they line and they furnace would light do you believe my inductor motor could be going bad?

That is highly possible you would have to check the amp draw during operation. You could also have a restriction in the line... remove the line completely and blow it out, careful not to spit while your blowing, lol. Also may have a restriction in the exhaust pipe. Check for the restrictions first as they would be your cheapest fix. Let us know.
