Need a good mechanic in the OKC area, I have an electrical issue that I can't figure out myself .
If you mean the secondary air system , I tried that with no luck.try disconnecting the air diverter valves to see if they are pulling the ecm down? seen that a few times
Have you traced grounds yet? Make sure they are clean with no corrosion on the block and frame locations.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.
