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.

With the key in the on position, do you have 12v at the ends of the pump leads? Running the pump off the coil is a bad idea. Post a picture of the relay board as it is currently configured. When you connected the pump to the battery, was that with 2 wires separate from the harness?

I have ZERO volts to those wires and also Zero volts at the Pin 13. The only thing different from stock is the ground to enable fuel pump relay connected to the car body.
