My cold start valve is not opening under normal cold start conditions - no spray. My cold start valve does not open when the thermo time switch is bypassed and jumpered out - no spray. The Cold Start valve sprays fine when I supply it with +12V and ground directly at its connectors - perfect spray pattern. Lets see if I have this right... It looks like ground runs from the hot start relay socket, through the thermo switch, to one terminal, and the cold start valve using a blue/black wire The +12 is supplied from a white/red wire at the starter? So, with the jumper installed I should first look for continuity from ground to the terminal on the cold start valve which ties to the blue/black wire, if that is good then I hook back up to the thermo time switch and check again. I then look for +12 on the white/red wire while cranking? In theory it sounds ok, but I think I'm a little off here - any help or suggestions? Thanks...
