My check engine light is on, and I have changed the spark plugs and coil pack for cylinder seven however, it has not fixed the problem. The pigtail connecting to the fuel injector has been probed and is not getting power. I have probed all of the other fuel injectors, and their pigtails are getting power, however, seven is not. what could this be? I have people telling me that it could be a lifter issue and I have people telling me it could be a computer wiring issue.

 

What are you driving?
