I have a 2008 f350 with all the deletes and it has a spartan tuner and what not.. I went to tune it to the tow tune and walker away from it and when I came back it wouldn't start. The red anti-theft is blinking and the programmer won't read codes or let me put it back to the old tune. I have disconnected the batteries for 15 minutes to let it reprogram its self and charged the battery thinking it may be low but it still will not turn over. Please help!!
