anti-theft system : car will turn over but no start. code came up as anti theft--- new module, new keys/code? Is this a fairly common problem on a 99 stang ( 178klm's)?


Asked by Aug 20, 2007 at 12:48 AM about the 1999 Ford Mustang

Question type: Maintenance & Repair

I tried my second set of keys- still no start up. I was told I had to take it into the dealership for specialized testing ( ECM .).
Has anyone had this type of prob.?-- sound familiar? Any advise would be helpfull! Thanks.    --  C.V.

Take it to the dealer as you were advised. Perhaps the new module was not properly programmed with the VIN before being installed, or perhaps the module was not set up to use the anti-theft keys, and so is responding like your keys are unknown to it. At any rate, it sounds like a BCM or ignition module problem. Have your keys reprogrammed at the same time.
