I'm trying to start an LS3 swap into a restomod for the first time using a 2015 Camaro E38 ECM. I've done a few of these before and have never had any problems. But I can't seem to get a spark on this one. When I crank the engine over, I get an RPM reading and the injector duty cycle goes to about 4%, but I can't seem to get a spark.
I started logging fuel cut type and cam sensor count and found the following.
1. Fuel cut type is "none" for the first few attempts, but changes to "unknown 00 014" eventually.
1. The cam sensor count isn't going past 0 (which makes me think this is the issue)
I tried another camshaft position sensor from a running engine and it didn't change anything. I did confirm I have the correct camshaft timing gear.
Any help would be greatly appreciated.
