Onefastmustang is correct. You should check all of the grounds. Question, Is this a recently completed kit? If so then maybe you need to add more grounds. Did you make sure that you removed the paint in the area that the ground wires attach? This would insure a better connection. If this kit has been on the road for a while (and working correctly) especially in a moist climate there more than likly is a corrosion issue. Remove all grounds and clean the areas of all corrosion. If all of this doesn't work CRII sells a new wiring kit that is designed for Chevy application. The manufacture of the kit is easy to work with and if you have a special wiring setup that the kit doesn't cover all you have to do is call them and they will walk you thru what wires to hook up where you need them. But first check all of the grounds for corrosion and/or paint.
