The ECU controls the main relay. The main relay operates the fuel pump and supplies power to the injectors. The main relay would not cause you to lose power to the fuse box, interior, etc.
So, what describe more of your symptoms; for example:

There's absolutely no power to dash when I turn key to on position, everything remains dead. check Horn still working small lights are control by the passenger fuse box so the lights still works, check headlights and driving lights still works, power lock works, Power window don't work power to the inigtion don't work well I think all those related to the one that control the fuse box.

It sounds like the problem is in the ignition switch (battery) circuit.
If you have a voltmeter, multimeter, or test light; check the fuse(s) to see there actually is power running through. For example, at the under-hood No. 21 (50A) large fuse I previously referred to. Attach the negative lead of the tester to chassis ground, then touch the positive lead of the tester to one side of the fuse, then touch the positive lead to the other side of fuse. There should be power on both sides of that fuse. |

I actually try that the fuse is fine and I tested on that and also on every fuse including the 100A fuse, I even took out the 21(50A) fuse and jump the wire see if thats the problem nothing move still no electrical going through the inside. (can''t believe trying to fix one thing and **** up another thing) |

The No. 6 (15A)fuse in the driver's side under-dash fuse box affects the ECU and cruise control. The No. 9 (7.5A) fuse affects the cruise control indicator light in the instrument panel. I don't believe there are relays in the brake light switch circuit or cruise control circuit. |

I finally figure out my rooky mistake, feel like a dump ass and really thanks to you and apreciated all your help. When I did the tests with the wires on the ignition somehow I move the loom of wire that hook up to it and it turn on the radio, and while doing the black wire test and other test I move it and some how the whole car came back on. I look down where the fuse box is and the whole loom of wire from the steering has a big connection that goes in the back of the fuse box was loose so I push it hard back in and wala everything is working again LOL. Thanks alot again. |
Glad you figured it out and reported your fix. :)
