Found the controller but have not tested it yet. i found another thread that suggested to apply 12 vdc directly to the pump to see if it works. i did this and the pump turned on. i reconnected the pump and the relay and again when i turn the key nothing. Will the pump burn out with a constant 12vdc applied while driving. So How can i distinguish between the Controller and the ECM (possibly)...it does seem odd for the ECM to ONLY be bad in reference toward the fuel pump. until i start the car i don't know if anything else is not working yet. I searched for trying to make a distinction between the two and it pulls up a huge amount of info to go thru so if you have any insight PLS let me know.
