Whelp the fuel pump quit again. Following these instructions from this page ( THANKS RON!!! ) I found a bad relay, brown base.

Fuel pump relay's coil gets 12volts with key on, but has no Ground so relay doesn't close
That 12volts comes from EEC relay(brown base), it also powers spark and fuel injectors, along with EEC(computer).
With key off one of the slots in Fuel pump relay base(green) will have 12volts, thats the battery power via fusible link
Turn key on
A second slot should now show 12volts, that the power from the EEC relay, if no power then either the wire from EEC relay to fuel pump relay(red wire) is bad or EEC relay or it's fusible link is bad.
If second slot does have 12volts then fuel pump relay is not being Grounded by the EEC

If there is a 5th slot(below 87) ignore it
85 and 86 are the Coil connections
87 and 30 are the Load connections, 87 and 30 are connected when relay closes, these are the slots you jumped to get fuel pumps to run
So either 85 or 86 should have 12volts with key on
The other one would be the Ground wire running to the computer.
Might be a light blue wire
Red wire should be the 12volts from EEC Relay
You can add your own ground splice if that wire seems to be the problem, that will get you up and running and won't hurt anything because thats what computer does
Fuel pump will still go off with key
