No delay. It should be immediate.. and it does it multiple times if it does not detect flame. If it does not succeed then the check light will come on.
If you have a dvm, put it on 20 vdc and put the + lead on the incoming signal wire to the igniter and see if it provides a 12vdc signal. If it does then check the spark wire ceramic part of the electrode to see if you might have shorted it out or if there is even a fingerprint on the ceramic it will use that as a path to ground and no spark. In other words it could be sending a spark but it is getting shorted to ground somewhere along the way to the tip of the electrode. If the electrode is too far away from the burner it will not spark. 1/4"....
