@gnob, Sorry I have heard the Toyota term ECT as Electronic Controlled Transmission. Didn't realize you were talking about the Engine Coolant Temp Sender. My Bad
@sirdeuce, I did replace the Engine Coolant Temp Sender a few months ago with one I bought from LC Engineering. Unfortunately it did not resolve the problem. I recently did a fuel pressure test and it held pressure when shut off for quite awhile. I ruled out a leaking injector because of that. What are your thoughts? I contemplated leaving the cold start injector hooked up but pull it out of the plenum slightly to see if it leaks. I also read in another forum a guy that pulled his fuel injection rail out, left the injectors in it, did the fuel pump jumper at the diagnostic port to pressurize it and found a leaking injector.
