Here's a wiring diagram for ya for the sensors to the ECM



And another for the VLOM, sensors and ECM



Don't forget to check the engine fuse in the underhood fuse block.

Ty so much for the assistance. I went into full diagnostic mode yesterday. I found that I have spark to the four coils on the driver side. But the four on the pass have no spark. I swapped out two of the coils to the other side and they had spark. Tells me my coils are good. I have power to the harness on the pass side but no spark. I want to reiterate that I got the truck running once. For about 1 min or so. Turned off and now where here lol.

So, a crank sensor code and the right bank coils are dead. If I weren't on my work laptop I'd be able to look up the wiring schematics. But, there's a common ground issue that will kill the left bank coils. Perhaps you have a loose ground or damaged wiring on the right bank that caused you to lose the CKP sensor and the coils? CKP is on the right bank but I don't recall any grounds on that side other than the one on the RH cylinder head in the front, above the tensioner. The other circuit that comes to mind is the one that feeds the CKP and starter solenoid. It runs along the oil pan and across the front, behind the crank pulley in that plastic shield.

I agree with Chris, that there is a ground issue. Check the ground on the front of the pax side cylinder head. There should be two wires that terminate there. One of them is for the coils on that side.

Not sure if this motor is the same as LS1. However, the LS1 has a ground on the back of the driver's side head.

Something went wrong with this build. Ended up being catastrophic failure in two cylinders. Hence the no start. After a lot of testing and diagnosing all electronics checked out okay.

@TTRZ71 Sorry to hear that, what’s the current status and plan of action?
