If you have a code key stick it in the diagnostic plug and see if you can get the ses to bring up any codes. Other than that it sounds like a short.

After looking at every, fuse, relay and fusable link, i come to find out that the orange wire that powers the ECM was repair in a couple spots! I replaced the whole wire, car now runs and drives like a charm again...
