No the battery does not need to be installed because when you disconnect the injector cable you are isolating it from the battery and cpu. If you're not reading anything (which happened to me also) then the injector is bad. Make sure to short your leads together to verify your meter is working properly. You can also test the new one before installing it.
Take a look at this j-bender.com/?page_id=154 Your car is less than 3.58% of the total made like that. Very rare. and 3% for 1990. That color combination was only made in 90 and 91. Just something to keep in mind. Take care of your interior as well. You will have to shell out big bucks to replace plastic pieces and carpets in blue. Id strongly recommend tinting the windows and using a windshield sunshade if you keep it outside.
THANK YOU FOR THE VIDEO, was able to diagnose that my 3rd injector was bad and plan to change it this Sunday 👌👌
Thx for the video,,,,hope the Z is still running....
All the best
Thanks
Does the battery need to be on the car to ohm the injector? I tried to ohm one injector but it didn't read anything.
