So far i haven't been able to start my LS3,
We have done everything that needs to be done and now we think it may have to do with the Park Neutral Position(PNP) switch.
The reason i am saying this is because my GM tech has done everything possible and the only thing we can see is that the PNP Switch says it's in gear according to the Tech2.
Anyone know where this is located and how i can bypass this.
I will ask my GM Tech tomorrow if i don't get an answer today but i thought maybe some friendly forum member may have the answer for me so i can work on it today
Thanks!

its in the transmission, it prevents you from starting in gear. Only allows you to start the motor in park or neutral.

Hey Christian, thanks for the info.
Here is what Werks had to say:
The PNP switch wiring is found
at the harness on the OEM shifter mechanism,

but i would like to know if anyone would know the exact location and schematic of the wiring.

Schematics can be found on the Autozone site (just register (free) and then enter your car info and go to the 'maintenance' pages IIRC).

From what I can see on my copies, there's a bunch of switches (well, four) inside the Trans, and a number of wires into the ECM. The ECM then determines the state from these and signals/enables the starting circuitry.

Thinking about it, all the above applies to a 'normal' car. You probably have a different transmission and ECM, right? So all that may not apply.

The tranny is different, the ECM is the same. I'll check out the site.
thanks TomatoSoup
