lly injector problems

[Leland]

i have a 04 lly that ive put 3 sets of injectors in in the past year and a half. i am not running any tunes and keep getting stock bosh injectors. also this before this last time i got a new injection pump. any ideas?

What sort of failures are you having? Where are you getting your fuel? What type of filters are you running? Are you sure they are genuine Bosch injectors?

 

[GMC-ya!]

Probably common sense but is it the #2/7 injectors causing the issue?

 

[Leland]

im not sure of the brand of fuel filter off the top of my head but i always get the most expensive from advents alto. the injectors keep blowing out either stuck open or stuck closed. mainly cylinder 3 has had to be replaced every time. and im paying a diesel shop to put bosh injectors back in

Bet it’s the harness and they’re not changing shit.

Moved over to LLY section. Something is up that hasnt been checked. The guys have touched on the possibilities. Listen to them.

Find you a new shop. They obviously don't know what there doing. Or they do and just screwing you

If your getting good fuel no reason for injectors going out

Checking wiring seeing its an LLY. Then I would make sure they are putting OEM Genuine Bosch injectors in the truck.
