I have just bought a 2002 f-250 with the 7.3. I bought a ts 6 pos chip for the pcm and installed, caused the truck to have a crank but no start problem and never did start. cleaned the pcm even better and still nothing. I can remove the chip and works fine. So I decided to get rid of the chip and just go with a programmer so I have found a used superchip cortex and tried to install it after getting it all updated and talking to superchips it still will not allow me to program the truck. has anyone had a PCM problem that would cause this or is my luck with a new ts performance chip and the superchip just horrible lol.
Thanks
