I just installed the dsm 450cc injectors with the resistor pack to run them. Whenever I turn my car on the ignition I can hear a clicking noise coming from the resistor pack. Is this normal? I know injectors are supposed to make a clicking noise but I thought it was only when the car was running, and it wasn't supposed to be noticeable except with a long screwdriver on them. Any help on if they're wired wrong or if it just does that would be great. Thanks.
