Fuel pump just quit Options

[surfdogskier]

So I had everything working well on my carb conversion with the exception of the fuel pump which constantly ran unless I pulled the ground wire per SirAndys carb conversion write up.

Now my pump will not work at all. I direct wired it to the battery to see if the pump was good and it worked. I connected a 12 volt wire to my relay board at the black/red wire #13 connection and it worked. So no issue with the wire. However something on the relay board or relay prevents it from working when the key is turned on.

I was going to wire it to the 2 other points on the relay board to get 12 volts (T4b and the #12 pin on the T12 connector). However, with the key turned on, I am not getting 12 volts to either of these. the T4b, I am getting 2 volts and the pin 12 on the T12 I am getting 4 volts.

My only other option to get 12 volt power is to connect to my coil but I have read this is not a good idea.

Looking for some guidance.

Which ground did you pull? Are you talking about the one that's labeled "Ground To Enable Fuel Pump Relay" in that picture? I'm not familiar with the carb conversion write up.
