Shorted injectors

[LB72004]

anyone have any clue on what would cause an injector to short to ground? this is the second one in several months. the codes that popped up: codes: P0201, P0204, P0206, P0207, P2146

the injector that shorted out(to ground) was cylinder #1. last time it was cylinder #5. it ends up shutting down the whole bank and it suck to drive.

the first time it just out of the blue went into limp mode and CEL come on and i limped it to work. i ended up limping it home and over the weekend changed the injector. at first i thought it was just a fluke but now i have another shorted injector.

this is on an LB7 duramax not the infamous LLY

Thanks Jason

Check the wiring harness behind the alternator as this is a noted spot for the injector wires to rub through and short out.

Thanks,

i was referring more specifically to the actual injector being shorted out. when i removed the last injector i was able to able to test it with my meter and see that the coil was reading zero ohms to the body of the injector.
