LS3 Swap - not cranking
Hi All,
First time posting here and need some help with a LS3 swap.
Full engine, gearbox (manual), pedals, harness and cluster from 2010 Camaro transplanted into a truck project. Someone else installed the harness and have trimmed out some elements (ABS, Airbags, etc.)
I can't get the engine to crank. I have confirmed that the 5V supplied from the BCM is switched correctly at the ignition and returned to the BCM. On HP Tuners, I can see "Crank Request" turning to "YES" when the key is turned. The "Starter Relay" remains "Off", however, and no voltage is supplied to the starter relay.
Some more info:
- VATS 1 and VATS 2 disabled
- Starter Fault checks disabled
- Bridging starter relay leads to successful crank and start
- Clutch switch status correct on HP Tuners
Any help would be greatly appreciated.

Are you getting any codes?

I managed to get her started eventually.
Turns out that despite reading the Clutch Status correctly, disabling the Clutch Interlock did the trick. Not sure how or why this worked, but I'm happy that I have a running motor.
