How did you determine there is no (and what's not) communication with the ecm? Nothing? Our GSE mech here at the ramp is as sharp as the come, plus he is a Tundra guy.2008 Tundra , no communication with the ECM. Vehicle will not start. Have tracked all I can think of and google foo is all over the place. Have already spent money and time trying to shade tree this so a pro is needed LOL.
Have you washed the eng bay lately? Can you get and ECM info at the OBD2 connector?
