Hey guys I'm at a standstill with my ls swap. The motor was cranking and running fine and now she won't start. Everything is new and I even replaced the ecm thinking that was the culprit and it still spins over but no start. The spark is weak and orange not blue like it should be. All my wires are grounded and connections are good. This just happened out the blue and I'm stumped. Does anybody know what else could cause the weak spark and the engine not to start at all?

Are the plugs wet? Make sure you have fuel at the rails. I would double check your coil grounds.
