Hello Scotty, I have a 2013 toyota tundra that has electrical gremlins. First off I'd like to say that I've replaced the battery and alternator. The problem I'm having is no power at all, if I hook up jumper cables, dashlights come on and the truck will start and run however if I Rev up engine some warning lights come on and gauges go crazy a nd if done enough times the truck shuts off and has absolutely no power to anything again. I had someone put a reader on it and they said it threw 22 codes prior to deleting it so I have no idea what codes it threw, I also hooked up a reader for myself to see if the codes would return but the only one that comes up now is a p2714 trans solenoid d stuck. I don't think that's my problem but I could be wrong..I saw a video where you had no power to the car, hooked up a secondary battery, still had no power then you changed the ignition and it started right up. I don't think that's my issue either because when I hook up a secondary battery it'll start. This problem has been driving me nuts for a couple months now and I can't seem to figure it out. Can you help me
Well, since the entire electrical system of a car is connected to itself and the main computer I would pray it was just a solenoid to replace the solenoid that might fix it all. Because if it's not that odds are you'd have a bad main computer and the problem with that is Toyota The computers rarely go bad unless there is some type of wiring or sensor short. So if you replace the computer and that short is still there, it would destroy the new computer also
