I know this is already posted but hard to find the one i need so here it is. I installed the F6 tuner and my check engine light stayed on and didnt start. I Unplugged the batteries reseting it alowing it to start then i changed the chip to one of the settings then the truck died. I reset the batteries and couldnt get it to start again. I removed and played with the chip cleaning the connection several times of which never worked. The PCM is still functional as i took out the chip and it started right up.
