Default L99 into a LS3 2014 Camaro No Start

Put a l99 into a 2014 LS3 camaro with a LS3 engine harness. P340 code. Has 5 v and ground at the cam sensor but appears no Wave sig coming from sensor. changed to new sensor same problem. Diagnostic show crank sensor counting and has 5v. Cam sensor shows 5v but not counting rpm. Since the the LS3 harness only has 3 wires to cam sensor that is what I used with a LS3 cam sensor. There are now no wires going to the secondary cam sensor off to the side of the L99 timing cover. The 3 wires are blue/white trace closest to the block, brown wire then blue wire. I also checked the brown wire to ground and it is working properly HELP! driving me crazy

Did u cam swap this?? If so the cam sensor is to far away from the cam gear to read it. This happins if u reuse the vvt cam cover. The correct cover is a ls2 cover. It pushes the sensor closer to read the gear.

If u still have the vvt setup, might be best to delete it with matching harware i listed above.

No cam swap. Took the L99 out of a running 2014 Camaro auto thats was totalled in the rear. I removed the motor, changed the harness to the manual harness and removed the auto trans and put the manual trans on it. As far as I can tell the LS3 and L99 cam sensors are the same with the same depth.
