from the sounds of things you may have a bad Ign switch and the constant turning is getting it to work One thing you may want to get to help in the future is a copy of the;
Ford workshop manual on DVD. Can be obtained from seller "morpheousking" on e-bay. Cost about $10.00 Much better than Clymer, Haynes or Chilton and also includes wiring diagrams
Don't waste your money on a Clymer, Haynes or Chilton Manual.
It is well worth the $10.00 just make sure you get the DVD for your year as the seller has different DVD's for different years
They also have the procedures for checking out different components, and also making repairs to other systems mechanical/electrical
