I changed my rear dif fluid and when I tried to start the truck I heard it try to start then nothing. No lights no power to anything. NOTHING. I'm going to look for fuses while I wait for a response. I don't have any power to anything. My key fob or dash, nothing.

 

Well nothing you did in the process of changing the differential fluid should have affected that. I'm sure you already are but check the battery and all the connections as well as the fuses.

 

I just check and pulled a couple of fuses. She is up and running my dad said that certain cars have a circuit breaker that will trip if for example the head lights ground out. Whatever it was it fixed itself and no codes. Thanks for the help.

 

Glad you got her up and running again, hopefully it was just a random hiccup.

 

Well it did it again, and upon further inspection the terminal on the negative side of the battery was a little loose, enough so when the engine began to turn over it jumped up and opened the circuit.

 

welcome to the world of electrical system trouble shooting.... always start with the power supply, haha. glad to see it fixed.

 

Me too. As soon as I saw the power go out I walked right to my FLUKE and turned it on to check for power. Such a pain in the butt!

 

Glad ya figured it out, I hate electrical, its always a PITA

 

ya like working on the lighting system in a 92 Celica for 4 hours, and finally being able to have allllllll the lights working on it...

 

That's what you get for buying a beat up Toyota
