Hi my 1990 7mgte supra have some kind of problem with the interior, nothing works, the light of the fuel is always full, and the light of the doors don't work and it dosen't start... the only way it can start is by jumping it and when I accelerate it a little it bring the dash to light but it does some sound kind before it bring to life the dash... the dome light doesn't work... the only guage that work are the Speedometer, tachometer, temp, oil and boost but all of them after i acelerate it... somebody knows why does it happen... i hope it's some kind of relay

Your first step should be checking all your fuses associated with the malfunctioning circuits.

Check the fuse box in the driver's side kick panel, and near the battery in the engine bay.

Initially i was thinking that it could be the alternator because when i give the rev up like 3000 the light come up but the car can run 3 days because the sudenlly the batery is dead after that

You could bench test the alternator and battery for a start. If the lights work after awhile, I wouldn't think the fuses are bad. They are usually good or bad. No inbetween that I've ever seen. gl.

Ok it sounds like a good idea to test the alternator is really curious, because i can put the keys in it and it won't start i have to jump it to start it is like the whole interior is dead? And the fuel gauge is always full do you think i can replace each guage for a autometer gauges and fix the interior problem?

One thing at a time.

1.verify alternator is doing what it's supposed to do.

2. verify that you have a good battery.

3. As Sheaff said verify fuses are all there and good.

4. Check your battery connections. ( I just replaced my battery connections and was thankfull that it was such a easy fix vs. searching for a loose wire.)

Once those are done make a list of what's not working. No sense getting new gauges if that isn't the problem. Unless of course I'm working on your car and charging you....if thats the case I'll just start replacing things and hope I get it right later than sooner.
