Has anyone else found that their truck starts fine, in fact perfect, without the cold start injector? I removed mine about a month ago when I was trying to diagnose a hard warm start condition. I lost the clip that hold the connector onto the injector so it's been disconnected since.

We've had some really cold mornings already, and my truck fires off on a cold morning perfectly, the same as when the CSI was hooked up.

Is there really any need for the CSI?

Mine will barley start without it

Are you sure it was working correct to begin with?

No I'm not, it could have never been working for all I know. But even if that is the case, it starts perfectly without it when cold. If it started the way it does cold all the time, then I would be psyched.

I pulled it off to start diagnosing a warm start issue, starts like crap when warm. But it got too cold too quick for me to start pulling connections off of sensors and dealing with cracking old, brittle, cold connectors. Lost the CSI clip and just left it disconnected, still starts perfectly when ice cold.....still starts like ˟˟˟˟˟ after sitting a few hours.

Mine does the same thing. Toyota has a bulletin about it

#2 sounds exactly like my issue. Do you know if they had a bulletin for the 3VZE with these conditions?

Also when it says to "Increase Temperature", is that an ECM setting, or is that replacing a sensor that is calibrated differently?

It is replacing the cold start injector timer with the updated one, the pic is just showing what it is fixing. I don't think that they have a bulletin for the 3vze, the one above is for the turbo, but I figure if that has the same problem, it must fix it for all the engines. I think someone has a post about going around the timer switch since a new one is pretty spendy.
