First, install a brand new needle and verify that it is facing the correct way and it is the proper needle for your machine.

Confirm the bobbin has been installed in the bobbin case so it is unwinding the bobbin the proper direction as you pull the bobbin thread.

If it still will not pick up the bobbin thread, open the bobbin area of the machine and watch the needle action as you hand-turn the handwheel. You may see why it is not picking up the thread because the needle could be arriving too soon or too late to intercept the bobbin thread. If this is happening, the needle/hook is out of time. Take it for service.

Either the mechanism that holds the presser foot in place is broken or defective or the presser foot is not correct for the machine.

Did you loosen the handwheel to wind the bobbin? If so, it needs to be tightened before the bobbin winder is released.

You will need the service manual if you are planning to attempt this yourself. For one thing, needle height and timing are interrelated; the same symptoms that indicate that your machine is off its timing can be caused by an improper needle bar height, and the manual will give you the specifications for both.

Go to Sewing Parts Online. I tried there and your machine was not listed, but if you send them an email, they will be happy to order it for you.

Your needle could be bended or high is not correct. If this is not the cause you may need to adjust the timing.

Your thread choice depends on the fabric weight and type. Denim needs a different thread from a sheer fabric. See page 49 of the manual: http://www.singerco.com/uploads/download/a719909a6ca001462cb1c2536a04506fa9ff327c.pdf . (That's page 55 of the PDF.)

Beyond that, you want to buy a quality thread that hasn't been exposed to a lot of light (particularly UV light). Many recommend replacing a spool that has been out in the open for over a year. I've had good luck with Coats & Clark.

I hope this helps.
