How do I test my obd2 port? My tester is saying it can’t link. I’m having a problem with my injectors not firing

 

I’d start with if it’s receiving power at the port. Google OBD2 Port not working. There’s many YouTube videos. Many things from simple fuse checks to using a test light. Can’t give you a specific off the top of my head. I’m just a diy guy but have found numerous channels on YouTube very helpful. Good luck.

 

Thanks I’ve looked up many different things to try and get it to work.
