if i have the injectors off with the clips on and turn the key on its soppose to make a click noise, it doesnt....but when i test the injectors on the battery they click really loud. the clips to the injectors do have power... maybe bad ground?
or not enogh voltage or what??anybody know where the ground is located? any imput would be appriciated thanks.

 

I don't think it will click if you put it on the on posistion, engine needs to be running or cranking for injectors to get a pluse signal.

 

but when i turn the key on, the clips get power so i would imagine they would click..

 

nope, the ECU is not pulsing the ground, they will only "click" when the CAS is spinning, ie. cranking or running.

 

Remove the cas and leave its electrical plug on. Turn the key to ON. Then spin the cas's gear. The injectors WILL click as the cas is turned and the sparkplugs will FIRE as you spin the cas. This is a good/simple test to see if the ECU is outputing to the injectors AND testing the ignition/coil circuit to see if the plugs will fire.
