I've been hearing there's a relatively recent TSB where GM now replaces all 8 injectors when one fails ... where can I see this TSB?

I've got less than 2500 miles on my '04 Dmax & am already dealing with injector failures

It looks like from his other posts, that he's got an LLY...


The TSB for the replacement of all eight injectors only applies to the LB7 engine.


IIRC, Patrick had an LLY come in that looked like injector failure, but turned out to be the pump. Hope it turns out okay for you since both pumps and injectors for the LLY seem to be in short supply and may have been the cause of the recent hold on new trucks for a Bosch problem.

is it injector failure or dealer diagnostic failure?
