How can I test the fuel injector without having to remove it to see if it is bad. The injector I need to test is under I belive a plenum or something but is very hard tom even see so I might just have to remove that in order to test it. Basically I would just like to know if there is a certain tool or something to be able to test it.

Disconnect the injector harness and measure the resistance on it with an DVOM or use a noid lite and check the power and driver circuit
