I am working on a 08 G8 GT single turbo in speed density. Fuel is E85. If I start the car cold or after sitting for an extended period, It starts and idles great but if I cycle the ignition and attempt a restart, it goes very lean shortly after starting and stays lean until it dies. I am attaching 2 logs. In the one from 10.14, you can see STFT max out but pulse width does not increase. I have verified fuel pressure and its steady at 58-60psi. I am stuck on this thing and in a time crisis now. Thanks Guys!
