Well, all my idiot lights are staying on. It started doing that before I did a tear down of my wiring and everything. But I was hoping it was a bad ground somewhere.

I know that it just sort of happened out of no where. I went out to my car one day and started it and all the lights were on in the idiot cluster. I parked my car and proceeded to do a ton of work. And now when I just put my key to ACC. All the lights stay on and don't turn off. Is this a sign of a dying ECU?

I am also getting no click or anything when I attempt to start my car. I turn the key to start and it doesn't do anything. No click, or anything.

Any info would be great! Thanks!

 

bad alternator or you have disconnected the wires to the CPU (not ECU).

CPU = body computer
ECU = engine computer

 

Location of CPU? I know where the ECU is, but I haven't heard of the CPU..

Thanks.

 

next to the fuse box in the drivers kick panel.. I have posted a picture countless times

 

That's alright. I wouldn't expect you to. I think I know where it is. I will take a look.

Thanks.

 

why are you even looking there first???

What is the voltage on the voltmeter in your dash?

 

I messed around in there a bit when I pulled my dash out to install my alarm system.

Anywho, I figured out the problem. Or, maybe not. With the key in ON position, all the idiot lights go on. But, when I start the car, they all go off. No longer going on in ACC anymore.

I think a ground didn't get connected.

Thanks!

 

no, not a ground... The relay in the CPU that turns the lights on, gets signal from the ignition switch and the alternator... if either fail, the relay does not kick on, and you get the idiot lights on.
