Can you do some basic fault isolation? If not ignore this
See if voltage is applied to the gas valve at the
appropriate time during the ignition cycle. If not find out
why such as loose connectors, bad control board,
differential pressure sensor, thermal fuse, manual reset
button, etc. This is not difficult if you understand the
basic operation of the unit and its safety check features.
If voltage is present, check the continuity of the valve
solenoid. If open, replace the valve. If not open, check gas
pressure at the valve input. If none fix the no pressure
problem. If present, call one of the hacks that post on this
group that will sell you a new furnace and then wonder why
it does not ignite.
Also check that the inlet and exhaust piping is not blocked
somewhere. It is common for a leaves to accumulate in the
input filter screen just above the fire chamber and cause
the differential pressure check to fail because of no or low
