I checked the ones under the hood, I think labled ecm-1 and ecm-2 they are good, I've unplugged and reconnected the (16? pin) plug numorus times, nothing. Is there a way to check power to the plug with it disconnected? Volt meter or test light. This motor ran great before the intake swap, it just leaked coolant. I wonder if all this style vortec intakes and injectors interchangable.
