84 Supra fuel problem ???

Thanks in advance for everybody's help, I have a 1984 Supra 5MGE w/1130000+ miles. The car was running great then after crossing a small depression in the road it started missing. The check engine light came on and I limped the car almost home. The car could only be driven w/o touching the accel. If I did the engine would immediatley start to die. Then it finally died and wouldn't restart. After sitting in the garage for about a week I could get the engine to fire when turning it over but as soon as the key was released it would die.
I pulled the fault code and it indicated the ECU. A Toyota serv. man said they rarely go bad but check for loose connections or loose ground. I did and all seem ok. I have checked for spark(ok at igniter and #1 plug). I checked valve timing and belt(ok and belt was replaced not long ago). I replaced the fuel filter and ran some gas out into a container (It looked ok). Approx. 5 yrs. ago I had a problem with the fuel circuit opening relay and it was replaced. I tested it, per the Haynes Man., Between terminals STA and E1 I get 29 ohms not the 30 to 60 ohm range and between IG and Fc 150 ohms instead of 80 to 120 ohmm range. Is this enough out of the range to be the problem?? I also noticed when the fuel pump check connector was jumped I did not get a "whirring" soound from listening at the filler neck. It was an "uneven sound" with a recurring clicking noise??? Yet it did pump gas into the container? So, after all this, is the cutoff relay resistance out of range far enough to be the problem or do I have to drain a gas tank 3/4 full and replace the fuel pump?
A few more quest. where can I get parts online and where are the online TSRM's located?
Thanks, Tom
