Have you checked the ECM's 'databus' plug for any shorts? I'd check for shorting to and from the ECM anyways. Make sure it has good power supply and ground lines as well...

======================== Did you check the battery and cables? You said it acts like the battery is dead. Do you mean it wont even crank?

How OK do they look. Pick them apart and clean them, battery cables, all grounds, grounding strap, any connectors on the starter....etc. Allot of times the rubber will hide some nasty white stuff underneath.
