Im with Raylar on this one,
Do you have access to anything like this?
http://www.powerprobe.com/powerprobe/PPKIT03.html
If you have a voltage drop issue due to corrosion or a bad harness a simple volt meter will not work. My friend had a similar problem on a acura, it would throw all kinds of codes none of which were valid. Voltage to pcm showed fine, voltage with my power probe and a 2 amp load showed less than one volt. A pin was backed out on a harness, causing voltage drop under high load.
Try the plus wires if you wish, might need them anyway. If theat doesn't work clean all main grounds, all main + connectors, disconnect all harnesses and check for pins backed out. Back probe all votage and ground connections to ECM using a power probe or loaded meter.
Good luck
