I was checking my Cold Start Injector (CSI). I noticed that it wasn't spray when the car was cold. I went to the thermo time switch(TTS). I checked the resistance at W, G, housing and compared them with the Factory specs in the WSM. It is in spec. I then cleaned it thoroughly and after reinstalling check for continuity via the G and engine. I also check continuity across the poles. My TTS is working fine. I then removed the CSI and checked it manually. (12V to it via battery) Atomization is wonderful. It also doesn't leak when pressure is applied to it. Now comes my question why is it not spraying? It must be electrical but where could the issue be? Does power come from the starter solenoid? Any info would be appreciated. The more specific the better. Thanks.
