I have a 2002 Camaro z28 A4, and I recently got a code p1626: Theft Deterrent Fuel Enable Signal Lost. The security light comes on and off whenever it wants, but the car still starts. Every once in a while the car wont start on the first crank but will on the second. Ive read up on that code and it says that it just a bad signal from the bcm to pcm. Would the bcm or pcm need to be replaced? Any input on your experience would help a lot. Thanks
