I was installing my alkycontrol meth kit a few days ago and everything was going fine, until I buttoned everything back up and tried to start her up...well I go to turn the key...and nothing, thought maybe I lost power leaving the doors open, so I jumped the battery with my other car.. and nothing...

The only wiring made to the car was where I tapped for my meth pump, which is the big orange wire under the ignition switch, now note that that is also where my aftermarket radio power wire is wired to as well.

When I turn the key to the turn on position: there is no crank, you can hear the fuel pressure, a click sound from behind the gauge cluster, and passenger footwell, battery and fuel gauges read fine

What I have tried so far:
Got a new gm ignition switch from the dealer
Replaced TDR relay
Checked pretty much all fuses..not one is blown

Is it a bad BCM?
When the key is in the on position, windows work, horn works, trunk button works, interior lights and headlights work...

What doesn't work when the key is in the on position is my alpine deck and the HVAC can not be turned on

When I pull codes and reset I immediately get back B0432HC and SDM1040HC..

Something must have happened with that orange wire, what controls it or what else does it do...starter? Could that wire have killed my starter?

What does the Security light do when you put the key.

You put in a new ignition switch, electrical or key cylinder?

Do you have a manual or auto.

I just resolved a similar issue and it was his neutral safety switch on the tranny that was bad.

Here is what the starter circuit looks like:

Mine is an 02 z06 so its manual trans

After some investigating, I connected my alpine radio power wire to the big brown wire, and my radio would turn on again, but not when connected to the big orange wire like it originally was installed.

So that leads me to believe the big orange wire is "bad" or not getting power....so how would I fix that?

LOL!!

Sounds like your IGNITION SWITCH contacts are burnt!! VERY COMMON!

Check all the "Hot oin ON & START" fuses for battery voltage.

Thanks for the input, but I'm a rookie to electrical components as you can tell....how would I go about checking this correctly? Thanks

Check both big red wires at the switch for 12v power. They are what feeds the switch.

Red - 12V in
Pink - Ignition 1
Brown - Ignition 2
Orange - Accessory
Yellow - Starter

You'll need a multimeter or a test light to test the various wires are the switch

I know the orange wire is not getting power, and if the others are not getting power as well, what is the fix for this?

Bill Curlee

Heres a schematic for you:



Also make SURE that the female pins are not spread apart and make POOR contact with the male pin in the switch:

If there is no power to the RED wires then you blew a fuse.
If there is power to the RED wires then the switch failed.

Problem solved! Thanks everyone, I have learned alot form this...

I checked the diagram and I rechecked the ign fuses...

One was in fact blown...I must be getting old since I didn't catch this earlier....moral of thr story...recheck, double check everything carefully

Bill Curlee

You have to LOVE it when its the SIMPLE stuff that kicks your ***! Heeeeeee Heeee HEEE!

Glad its fixed.

Use an ohmeter to test fuses from now on!!!
