Can you exactly tell me what settings you have put in all the fields in the drive mode and exactly the exposure setting. It is not clear how you have been setting them. Do you use MF or AF? It will try to focus before the shot so if no focus is found it will not take the shot.
I have set 7 seconds as intervall, 5 seconds as shutter speed, i.e 2 seconds between shots, not saving the progress and there is no problem with this set-up...
EDIT:
It will take the first shot but no more if it can not find focus. If pressing the menu-button between shots you will get info on the status of the intervall and pressing again before next shot will end the intervall prematurely.

Originally posted by K David So I've been testing my camera in interval composite mode some more. Here's what I've found.
When setting the time between frames, that's the time that lapses between each image (and is in addition to the shutter time.) I tested this by trying multiple-second exposures with both a two-second interval and the exposure+2 seconds. In each case, the interval (when it worked) what the number of second I input and did not take into account the shutter duration. So a 10-second shutter speed with a 2-second delay would be 12 seconds from shutter-up to shutter-up. With a 12-second duration, it was 22 seconds between. So that's how the K-3 is working, to remove any confusion about that.
I am not sure how to interpret this but the way it works is as follows:
The interval time setting tells the camera to "push the shutter button" every time the timer hits the interval time. If the camera is not ready to take a shot nothing will happen but the timer keeps on counting until reaching the set amount.
During the exposure the camera will be
unresponsive but in the paus it will respond.
The interval has to be longer than the shutter speed so if we want to take a number of 10 second exposures with 2 seconds between the interval has to be set to 12 seconds.
BUT: Sometimes the camera takes time to save to the SD card or process the image and therefor needs more than 2 seconds between shots so you may need to set 13 or 14 seconds as interval i.e you get 3 or 4 seconds between shots.
This to look for if it does not work:
Is the paus between shots to short? I.e is the shutter speed equal or longer than the interval time. Set a longer interval time.
Is the focus in AF-mode and can not find focus? Set it to MF.
Is the Long exposure Noise reduction set to Auto or On? It will kick in when using shutter speeds longer than 1.3 seconds if turned ON, in Auto it kicks in at arround 20 seconds. Turn it OFF.
