No voltage at the ECM can be a lot of different things. It's not the kill switch or the starter would not be spinning the engine. It being a 2001, it could have had a C5 meltdown. First thing to do is to take a meter and measure for power coming out of the FI/IGN relay with the key on. You should have power on the black wire all the time, power on the black/white wire and the black/yellow wire with the key on. You should have very little to no voltage on the red/white wire with the key on. All of these are using the battery negative post for the ground connection while measuring. Based on these measurements, we will know which way to go next.
