I’ve seen numerous threads of no start 2nd gen coyotes but i haven’t seen my specific case pop up. I have a 2017 pp gt that was sitting for a few months with no battery tender. I’ve heard only a few cases in which the pcm would no longer work causing a no start situation when the battery voltage is below 12v for a sustained period of time. I got in and pushed in the clutch and pushed the start button as usual and nothing happened, no sound from the starter just the fuel pump priming. The lights dim down a bit and the beeping from the many notifications on my dash stop but then resume after 3 to 5 seconds from me pushing the start button. I went as far as buying a new battery and hooking up my battery booster to see if it needed the extra power. Nothing at all happened, i went into the many fuses and relays to find nothing was out of the ordinary but i jumped the starter relay and it turned over just fine. The only other thing i could think of is a gt350 start button that came with the radio bezel that i replaced. I hooked it up to my scanner to find that a pcm fault had been detected. Should i go ahead and order a new pcm and have it flashed or is there something I may be missing. Any help would be great, thanks.
