2206 Chevy Monte Carlo
 

Hello all, I have a 06 Monte Carlo LT 3.9L
I have a no crank issue. When I turn the key on, I do not hear the fuel pump engage. When attempting to start, All I hear is a clicking sound coming from the internal fuse box assembly on the drivers side. I have changed the engine compartment fuse box assembly, the BCM, Starter, Ignition Switch, Camshaft and Crankshaft Position Sensors, along with the battery. Also, I have a Tech2 tool with a ECU P0315 (CKP) System Variation Not Learned code. In order to relearn the CKP the engine must be running.
I think I have tried everything taking I'm mechanically inclined, but I know there is something I missed. I can sure use some help here.

Correction on my current post.
i did not replace the bcm
