Welcome to the forums.

You aren't giving us much to work with.

On a call for heat...... the inducer starts...... then the pressure switch needs to prove by closing.... then the igniter starts to heat. Your problem sounds like an issue with the flue or pressure switch path.

Many furnaces have a control board with a fault LED in the blower compartment. See if your furnace has a sight glass in the door. Look thru and count the flashes. The codes are on the back of the blower door.

Furnace make and model?
Error code?
Is the pressure switch closing when the inducer runs?
