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.

I've never noticed a click(ing) from when I ran a resistor pack on my dsm 450cc's, but those injectors click loud enough that I wouldn't.

If you have the MS setup so that it gives a "prime" pulse on the injectors, the MS will turn on the injectors at powerup with the key, which is prob the clicking you are hearing. Resistors dont click, so thats got to be what it is.
