Like I said in your other thread, this is a classic symptom of a bad computer.

I agree, the TFI Module "control moduel" will not keep the fuel pump running unless the engine is cranking.
You need to replace the EEC Computer if you do not have a short to ground in the wiring under the two relays or the Fuel Pump Relays contacts are not welded together.

Nope, if the EEC Power Relay were bad the Fuel Pumps would not come on. This relay EEC Power Relay only makes power available to the EEC Computer, Fuel Injectors, Fuel Pump Relay Coil and various solenoids.

Did you ever check for fuel pressure at the rail while checking everything else out. Do you think you have bad pumps in the tank.
My 88 had new TPS, new regulator, new pumps (3), new filter, new reservoir new everything to get it running. It was just to two low pressure pumps to begin with. I did enjoy the learning experience.
