I JUST TRIED TO INSTALL A USED EDGE PROGAMMER I BOUGHT ON E-BAY (I KNOW , I SHOULD KNOW BETTER) AND NOW THE TRUCK WILL NOT RUN. AFTER THE INITIAL POWER UP STAGE, AND FOLLOWING THE PROMPTS ON THE SCREEN THE PROGRAMMER DOES NOT RECOGNIZE KEY ON WHEN COMMANDED TO DO SO, ALSO I DO NOT HAVE A GLOW PLUG LIGHT ON THE DASH, AND NO CONTROL OF OD LIGHT ON SHIFTER. I QUICKLY CHECKED FUSES BUT RAN OUT OF TIME , I WILL DO MORE IN THE MORNING IN -20 WEATHER. I HOPE IT IS A EASY FIX, BUT THE GUT FEELING IS BAD. ANY THOUGHTS WOULD BE GREATLY APPRECIATED. THANK YOU JASON
