Ok. So those of you playing along at home, bypassing the fuel pump control unit seems to have cured the poor running under 3 grand thing. Only been a day and a half but now it runs like it just needs some adjustment. Spark time probably. Now the fuel pump gets an even 12v all the time like most cars. Well. Most older cars at least. So, to answer the what happens at 3 grand question, the ecu ignores load inputs and just tells the fpcm to step up from 6-7 volts to 12.
The fpcm manipulates the ground side of the circuit. I wonder if this went bad previously and that's what killed the old fuel pump or if the pump went bad and was trying to draw more voltage than it could get... hhmmm....

Now that it is getting more fuel, the idle will occasionally get hung up around 1500 rpm as the Revs fall. Hoping that's just a tps adjustment. But I have the aiv/iacv on the list to inspect just in case.

On a bit of a side note. Anyone got a good hook up on o2 sensors? By the time you pay what the parts store wants for two of them you might as well buy a wideband.
