So my car won't turn on and start. I can turn on headlights and hazard signals fine Ive check the fuses in the engine bay and everything is ok

Turn the key to acc and on position, radio, idiot lights, wipers and turn signal not working.

Ive tried installing another ignition switch and it still won't turn on, I've checked the voltage from the Black wire and it got 12v tried to jumper the Black wire with B/W wire and nothing happens. Don't know where to look next

 

There is a Licorice sized wire that runs to the Engine bay fuse block that has a single connector.
If that wire is not hooked up your lights work but you got no power to the main fuse to start the car.Some stuff will work but the block gets no power to start the car.
It's hard to see but it is there,located towards the Front side of the Fuse block.It runs from the Alt to the fuse block.

 

Are you referring to the Black wire at the ignition switch. If so, then the Blue wire (ACC) should have power w/key to ACC. And the B/W wire in the same plug as the Black wire should have power w/the key to the on position.

 

Yes the Black wire with B/W wire in the same plug it got voltage when I checked, I've plug in a new ignition switch but its still doesn't turn on.

I'll check that connector on the engine bay styx see if its hook up or not

 

Do you get the wipers to work w/key to on w/the new ignition switch. If not check the main fuse and the wire powering it from the battery, the wire coming out of it and the wire it feeds below the engine fuse box (same item styx asked you to look at).

 

I found the problem its the black wire with single connector. Even if its connected its still will give you 12v from the ignition switch. I cleaned it with a electronic cleaner, put some dielectric grease and my car started.

Thanks for the help!
