I am helping someone out with an LS swap. Car had a GM crate E67 (newer 127 lb/hr limit) and was running fine. Guy bought a used E67 (older with 63 lb/hr limit) from a V6 and swapped it in. I copied over all the settings, re-did the injector data and MAF, disabled VATS, etc. However, it won't start.
The key on engine off log shows spark and airmass are ready to go...but the cranking log shows all values go to zero (no air, no fuel, no spark). Since the cranking log also shows 0 RPMs does that indicate a wiring/CAN issue (or would a VIN/VATS issue also show that as well)?
What did I miss?
