ECM failure? Also anyone in NJ area want to help out with a spare?

[fetherston]

Heyo, so was riding my '03 XB9S over the weekend after finishing my complete engine rebuild over the winter. Have about 150mi on the bike since the rebuild, and the motor just cuts out. Pull to the side of the road, quickly figure out there's no spark.

Get home and confirmed the following:

• Key on, lights light up, fuel pump primes, bike will crank, can smell fuel delivery, no spark
• Swapped around the relays in the fuse block and verified fuses, no problem there
• Have voltage but no pulsing ground at coil pack connector
• Have voltage and signal from cam position sensor
• Many error codes including 52,53,54,55,56 using the diagnostic jumper method

So couple questions:

1. Fried ECM? Is there a better way to confirm before I start hunting one down?
2. Anyone in the NJ area got a spare I can swap in to verify my problem?
3. What year/models are ECMs interchangeable with?
