Help anti theft not letting car start
I have a 2002 mustang 3 weeks ago my
alternator was changed later that day the
car died it would crank but not start
thought it was the PCM. Replaced PCM
did a parameter reset with keys car
started worked great for 2 days died
again. Towed it to a mechanic they
replaced the PCM they had the car 2
weeks. I picked it up yesterday the car
died 15x I had to have it towed back to
the mechanic. They test drove it and they
died on the highway. I was told the anti
theft was kicking in and that's why the car
is stalling. I think this was probably the
issue in the first place. Only nobody can
figure out why. Is it possible that
changing the alternator (even though the
battery and alternator seem fine) is
causing this to happen? Of not what is?
Please help I haven't had my car in
3weeks and have spend over 1000 btw
resetting the keys the pcm I got the pcm
the mechanic got. Labor ECT.
Have you taken it to ford to get re-flashed? Any Ford dealer should be able to run a diagnostic get you flashed & get you rolling in no time usually $75-$150 to get it done!
I had a similar problem .theft light started flashing 2 weeks prior to my 2004 limited edition mustang wouldn't start one night. Theft control activated somehow? it would crank but wouldn't start. so i held my old key that had broken earlier this year next to my new key as i turn ignition back & forth not attempting to start it. old key somehow reset or fixed new key cause theft light went off and car started with ease . could have been just lucky that day but it worked
