i have a 2000 f350 7.3 and a couple of the injectors were missing so i ordered a rebuilt set. i did the drivers side and the engine would run the die in a couple of seconds so i pulled the injectors and one of the o rings was bad so i replaced all the orings on the drivers sdie and now my truck won't start i checked the high pressure oil level and that was full. i tried unplugging the icp sensor and tried starting it. i replaced the cps. and today my friend had a mac scan tool and he checked the engine codes and 4 came up p1280 p1670 p1316 p1212 the check engine light wasn't on so they are proble inactive he cleared them and none of them popped back up. than he ran a buzz test and 3 codes came up p1294 high side open bank 2, p1278 #8 high to low side open, p1272 #2 high to low side open.
