Can anyone give me any good advice on having a cold start issue with the cold start injection/timer circuit aside from telling me to check the fuses?? (3vz-e cal) I have done some searching, doesn't seem like there are any topics related to this. #coldstartinjection #wontstartwhencold. I understand roughly how the circuit works. The starter relay gives power to the cold start injector and the cold start injector relay/timer, which has a ground controlled by the ecm/ecu. I am looking for someone who has had a similar problem and what they found to be the issue. I have not searched the entire ground circuit or the power circuit, but I am in the process. I am just looking for some advice from anyone who has been through the same process. Thanks for checking this out...

I'm also stuck in the same rut.
I did find a good video on YouTube about how to check the cold start switch
. I also saw a very poor video there on how to check the spray from the cold start injector. I have yet to find out exactly where the cold start injector is though.
