P1260 Fault in 1998 Mustang Cobra: Causes and Diagnosis After Engine Dies Mid-Drive

Model: 98 Mustang Cobra Fault Code: P1260 Posted: 2010-03-21 17:15

My 1998 Mustang Cobra died after being driven for about 30 minutes and turned onto my street. The vehicle now will not start. I've been researching the P1260 diagnostic code, which indicates a 'Theft Detection System' fault. Could this be related to a recent modification or electronic system issue? What are common causes of this error in a 1998 Mustang Cobra?

What components might be missing or malfunctioning that could prevent the engine from starting and running properly?

P1260 = Theft Detection System Detected - Engine Disabled. Have you recently installed any aftermarket devices such as a remote starter, alarm system, or aftermarket radio? These can trigger the theft detection system and cause the engine to disable.

No, I haven't made any recent modifications to the vehicle's electronics or added new components like a remote starter or aftermarket radio.
