6.0 DTC code po263

I just had a egr delete kit,head studs put in and injector nozzles put on. After driving for a few days about 100 miles my check engine light came on . It ran fine after it came now. Now after setting for a few days it had trouble starting. I think its a injector problem but not sure what do it replace the injector or it is a o-ring problem. thanks for any help

Well check and make sure it's plugged in or wires aren't rubbed through (chaffed) and then replace it. But I always hook them up to my scanner and do a injector balance test beforehand to make sure it's just the 1 injector.
