Default Reverse Jumped Battery

I am having problems with my 2004 toyota sienna, I bombed the whole electrical system. The main fusible link was blown and ECU, engine wasn't charging battery was done in a few peripheral fuses were blown. I have replaced the battery, alternator, peripheral fuses, engine would start but nothing else would work. I replaced the blown main fusible link and replaced the stock ECU with a used one, the engine would no longer stay running but all other electrical is working... Or so I think. I have had a new key programmed and ECU reset to try to get it to talk to the immobilizer, the key seems to have taken. The engine now cranks, starts for a brief second and shuts off. It smells as though it is running rich as if there is unburnt fuel, I have looked up other problems pointing to the crankshaft position sensor but I don't think that is what it is given the start of all these problems and for the fact that the burnt ECU was still able to fire the engine. Maybe the problem lies with the used ECU not being programmed with VIN and positions and stuff. I need help. Who would I call, talk to, or visit to get the ECU cloned/Programmed? Is there another underlying issue that I should be looking at?
