Sounds like it might be a lost ground connection. I would start there first and check all of the grounds in engine bay and console. Kinda odd some electric components work but not the others

Sounds like the 100A fuse located in the fuse block under the hood opened up on you. It's the one that is actually bolted in the relay block with 10mm bolts on each side-it's not a plug-in fuse as with the others. You will have juice to some ares but not to some others-by what you're mentioning.

It may look good, but one leg cold have opened up that you can't see until you take it out and check with a VOM ... I've been there and done that as well.

 

[danielbo91]

I already check it still nothing I already check it if it was broken or no still the same I'm giving up on this car .

Check your wiring to your wideband/gauges. Also check for any loose grounds in the engine bay, make sure your negative terminal battery cable is grounded properly. There is a ground on the starter as well, not sure if that would have something to do with it. It sounds like a wiring issue for sure.

Try all that what you you told me already I'm starting to think I need to pull the harness out and check the wires , battery has plenty of juice 12.33 volts , but only that's is working is stock alarm, headlights ,interior lights dash lights emergency turn signals but that's nothing is getting power is the fuse or relay that could be causing this problem

So no one can help me what can it be that I have no power everywhere

Well here's a video so you guys can have an idea what's going on

The first thing to do is remove battery cables, both ends of each, and clean them with a wire brush and sandpaper. Also clean whatever they attach to (battery post, body, engine, bolt). Then tighten them back up securely. You should have one large cable going from battery negative to body and a separate cable going from battery negative to a starter mounting bolt on bell housing.

Might wanna check the taillight relay. I know several circuits are powered through it. I had a problem where my headlights worked, but no other exterior lights worked. Ended up being the taillight relay. I'd check that and grab an electrical manual and see what relays and components are involved in the circuit. 9 times out of 10 it's a fuse,relay ,or component. Not the harness.

Danielbo91 did you ever figure this out? My car is doing the exact same thing

 

[Dstarperformance01]

I would check power and connections at ignition switch.

 

[danielbo91]

Man Is been years since I had that car nice way bring me back bad memory's from that car, it was the fuse box wiring harness I end up replacing the fuse box hardness and engine bay harness may want to check that
