Where is the pressure switch on trane xr90? Blinks 3 times and is not blocked or inducer problem.

What is the chain of events when the stat calls for heat? Ex: inducer (exhaust) motor comes on, igniter comes on... etc. Tell me where it stops if possible please. Thank you.

The motor starts running for 30 seconds then shuts off. Then tries again. Today heat is working. Very strange! Bewildered.
