Remove the pistol grip screw, and remove the pistol grip.
You should have the spring in the grip channel, then above it in the receiver channel, the selector detent smaller end pointed up.
Now with the detent in the receiver channel, use something like a small punch to push it all the way up while working the selector. You should have the position stops on the selector from safe to fire. If you are not getting a clean engagement, then double check the receiver channel to make sure that the bottom larger step of the channel is clean of debris, and the tip of the detent can move up far enough to engage the selector detents/track. If need, you can clean both steps of the channel with the correct size drill bits (1/8" for the upper channel, and 9/64" for the lower step of the channel).
Note here: with the selector removed and the selector detent pushed up in the receiver channel, you should see the pointed tip of the detent to about the flat section of it in the selector channel with the selector detent pushed all the way up.
Now put the grip back on with the spring, then recheck the selector again. Here, you are checking to make sure that the depth of the grip spring channel is not too deep, and not allowing the spring to put enough tension on the detent pin to correctly engage it against the selector detents. If you find such to be the case (spring channel too deep, the use something like a piece of Q-tip to fill in the bottom void of the grip channel the needed amount.

Also to point out, make sure that you have the correct spring and detent in play.
