No Spark After 4.3 to 6.0 swap
Hey Fellers, I just swapped a 2005 6.0 , pcm, harness, TAC and pedal into a 2007 4.3 with a stick. using the 07 fuse block and cluster. Everything went swimmingly until I went to fire it. I have fuel injectors, ckp signal, cmp signal. tac through the scanner but no spark. I have checked all of the fuses , I have checked the grounds,( 1 pass, 2 on driver.) Tuned out VATS but no love. Oddly I get no CEL. Any thoughts?
