I have a 1990 hmmwv that I recently purchased. It usually shows an amber wait to start light that goes out after a few seconds and the engine starts immediately. Today for the first time the light flashes then goes out and the truck easily starts. Why has the light started flashing. Do I need a new control box? I currently have a black Narteon with a yellow label.If I need a replacement what would be a good choice?
