turn on delay that is getting longer before fan cuts in lights or not depending on how it feels, if it does light it doesnot stay on very long, the burner goes off and leaves the fan running?

burner fails to light/intermittant
FAN keeps running
first thoughts are FAN & air pressure switch APS
if FAN delta pressure OK & APS switching OK would check pump flow switch FSW
if rubber diaphragm inside FSW making microswitch then would check ignition control board IGN PCB
