If you are unable to get any stitches at all then it could be your hook basket has spun out of position and it needs to go to a repair shop.
Hopefully it is just a matter of cleaning out the upper tension discs from any lint or thread that is in there. (Make sure the presser foot is up when threading so the discs are open and the thread gets down into them completly and that the tension dial is not set too low or on zero).
I hope this helps, good luck!

change the needle
clean under the needle plate where the feed dogs are for lint
also clean the bobbin area for lint & loose threads

If the machine did sew fast the the replacement motor, then the problem might be that the machine is getting gummed up somewhere. Pull off the top cover, remove the 5 screws from the bottom of the base plate, (4 large screws, 1 small screw), remove the base plate remove the 1 screw from the bottom of the free arm cover. Now you can see most of the moving parts. Spray a little WD 40 on all the areas that you see metal to metal rubbing together, both on the bottom side of the machine and the top side. Don't flood the machine and stay away from the motor area. Plug the machine in, lay it on it's back and run it full speed, or at least till it runs full speed. After you free it up, blow out the machine with compressed air, and reoil with tri flow all the areas again. Run the machine again, and you've started your own tail gate repair shop.

Bobbin thread being too loose is due to two possible factors. The upper thread may be too loose allowing the bobbin thread to pull it under the fabric, or the upper thread may be too tight in which the bobbin thread will pull up to the top. Try adjusting the top tension to see if you can correct it. If it doesn't fix the problem, take out the bobbin and look for a screw on the bobbin case. If your bobbin case comes out from the underside of your machine, the screw is on the side. If yours is a drop in bobbin, it will usually be under the faceplate so you might have to take that off too to get to it. Turn the screw clockwise to tighten the bobbin, counterclockwise to loosen it. Only go a quarter of a turn at a time so you won't overshoot the mark.Then try by re-threading and sewing.
The basic procedure for threading is as follows:----------
Note that Pfaff sewing machines thread from left to right, not right to left like other sewing machines. The upper tension discs should be raised at their highest position while threading, and the presser foot should be raised up until you thread the needle. Drop the presser foot right before you thread the needle. The prevents thread problems during use.------------- Insert a full bobbin and retrieve the bobbin thread through the thread plate. Raise your sewing foot and needle to its highest position; hold the needle thread taught with your left hand, lower the needle into the thread plate using your right hand, and then raise the needle. As you raise the needle, the needle thread will catch the bobbin thread, and pull it up. There should be a loop of thread intertwined with the needle thread. Use tweezers, your finger, or a straight pin to retrieve the bobbin thread that is visible through the thread plate, and pull it through the plate.Place the fabric under the presser foot, and drop the presser foot. Choose the stitch you want to use from the top stitch display, right above the top thread feed. Press the '0-9" button located on the sewing machine's front panel, and a display screen will come up. Input the thread number, and press the 'OK' button located on the sewing machine's front panel.-----------this is procedure. If problem persists.Remove bobbin and clean lint from bobbin and re-tight the bobbin properly, then check.This should help.Thanks.Helpmech.
