Multimeter help needed

[DNA666]

After a rebuild my #4 injector isn't firing.

Does anyone know how to test the fuel injector resistance pack, power transmitter, and fuel injector plugs on a 2G GSX?

before you do any electrical tests...maybe you should check the injector...make sure its not clogged....

If thats not the problem...take a multi meter and it should read 2-3 ohms for a good injector.

I moved the injectors around and #4 is still not firing.

Put noid light on it or measure voltage. If non, look for broken wire, blown injector #4 resistor (in metal box in center of firewall - 5.5-6.5 ohms), bad ECU or CAS.

follow the injector harness wire to see if has a cut in it....theres most likely a short

could be the CAS...dont think its the ECU.
