Was just wondering how I can test my fuel injectors to make sure they are good to go. Can I use my SGII for this

 

Not as far as I know. There are some codes for pulse width and on/off, I can post them up for you I f want to try them but I don't think anyone's got them to work correctly.

A high quality scanner like AE or the dealers IDS can do a contrabution/cylinder balance test which can give some insight into injector operation but really relates to the cylinder effency as a whole. There are some injector rebuilders who offer testing. You have to pull them out and send them in though.
