Ok, so I've been running the greddy turbo timer for sometime now and it's been working fine. But lately the car would just cut off and ignore the countdown!! I have no idea why. The TT turns on properly, counts properly while the car is driving then when its time to cut the car off and time for the TT to work, it doesn't. I have the relay installed to lock the doors while the car is running, I just don't understand why it is cutting off. Any help would be GREATLY appreciated.
