Correct replacement fuel injector

[Chevykid404]

My 2003 Yukon 5.3 has a p0200 code and after checking the fuel injectors, they are bad. I need to replace them. Does anyone know the correct fuel injectors or part number to replace the injectors? I have looked online and I am having a hard time finding the correct injectors.

You should have either the LM7 or the L59 (flex fuel) version RPO code. Rockauto should have both of those injectors.

How did you check the injectors? Did you try swapping them? You may have a wiring harness issue?

Some advanced bi directional scanners will have the ability to pulse the injectors.

L59, Vin Z is 217-1626/12580426

LM7, Vin T is 17113698
