Re: S.O.S. for SES light, codes and issues after injector and turbo upgrade
So really the only codes to worry about is the p1274 and the p1277. It means you have a high to low side fault. So I would start out by ohming the uvch. So you have issues with #4 (second back driver side) and #7 (farthest back passenger side) so to ohm #4 you hook your leads to pins 4 and 5, pin one is starting at the front of the truck. #7 is pins 5 and 7. If you get an open then you have issues and have to pull the valve covers to inspect. If your ohm numbers are below 1 and above 4 (I believe) then you have issues with the wiring or the coil itself. If it ohms between 1 and 4 your have injector issues and you need to send them back.
The hard start is due to air being in the hpo system and is normal but you need to fix your injectors first.
