ok its a '97 Gp 3800 non sc. The issue is there is no pulse or juice to the injectors. I can spray carb clean in the throttle body and it runs great while spraying. I have swapped out crank & cam sensors, icm, pcm, map sensor, throttle and mass air sensors, fuel pump. I have even opened up the whole loom and the wires all look good and i have checked them with an multimeter to see if they r broken. i havent checked fuel pressure but i have tried 3 pumps and they all kick in. Is there something i have missed or is there someone out there who has had a simular issue and found a cure? Just up and quit. shows a code p1200 injector control circuit. Thanks for looking.......
