this past week my truck was throwing a p0208 code and would derate power i read it cuts the whole back of injectors. so last night i tore into it and found the number 8 injector wire was loose (was in a hurry to finish it when i did injectors). so fixed that and it started later on i tried to start it again and the fuel gauge wouldnt move off empty. it has 3/4 of a tank. it will crank just fine but no start. tried a new ecm i had around and the gauge started working but still did not start. then i hooked up my v2 and it check codes and it said u1016 cycled the keyand tried to reconnect and it said pcm not detected. i need help im lost what else3 can i try i need this vehicle running
