Here is what I have done so far, replaced the ignitor, flame sensor, pressure switch, clean the hose(GMP 100-3, 80%) and took apart the vent that goes to the chimney and cleaned it. I lit a match to make sure the vent pulled the flame upward towards the chimney. Still no heat.

Thanks,

You replaced a bunch of stuff but you did not say if the furnace did anything at all.
Do you have 120 volts power at the furnace?
Do you have 24 volt low voltage at the furnace?
Does the blower fan run with thermostat in blower /fan manual mode?
