Thanks for the quick reply guys

here are the voltages for the fuel pump relay

wire koff kon kstart
pink/blk 0v 12v 12v
grn/yel 0v 0v 12v
red 0v 12v 12v
blue/org 0v 12v 0v

Should both signal wires be at 12 volts with koeo?

This is with the eec black/wht wire grounded properly. Yes, I hear a click coming from the eec relay and it does seem to transfer power from it's inputs to outputs. I tried another eec relay that I had sitting around and it produced the same effects.

By the way, most of the eec outputs are at 12 v when I stuck pins into the wires coming out of the harness. It just doesnt seem to respond to the self test or function properly.

mmmmmmm..... pete's thinking about a nice carb conversion.
