Singer model ce100 does not sew with pedal

Question

machine was bought new and never has sewn. tried to make it sew by calling singer to no avail. they have no support for this model in puerto rico.
checked sewing thread path and followed instructions in detail. machine does reverse but does not sew forward. lights indicate normal. could be pedal but replaced with other same model still does not sew. electrical is 120 volts. I was wondering if there is a problem with this model. have not tried to sew with computer since it does not sew at all.
