I have read many problems with injectors this week and was wondering what are the DTC's for your trucks. I wonder if they are all the same?:rolleyes:

Most of the trucks never throw a code, they just start smoking, end up with fuel in the oil or they become hard to start.Some may also go into limp mode when under heavy excelleration or when pulling a heavy load.

I think it depends on what goes wrong with the injectors. The return rates on mine were too high and it threw a p0093 code. that would be a p1093 on a newer model

I've only seen a cylinder miss-fire code. Otherwise it's diagnosed by high fuel return rate and injector balance.

MOST don't fill the crankcase with fuel BUT it's not unheard off.
