I have a 1993 Tracer that my family has owned since new. It has 103,000 miles on it, has a 1.9L engine, Auto. trans. I believe I need to replace its neutral safety switch because I have an intermittent no ignition contact to the starter when trying to start it in park, but when I shift it to neutral I have no ignition contact on the first try, then I get ignition and it will start. I cannot locate the replacement switch part. Ford parts told me the part number is F1CZ7A247A, but it is not available. Any suggestions would be appreciated. Thanks, Ed
