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. Attached image(s)

I do not know exactly why the fuel pump wire was not activating at the relay board. So I pulled the red/black wire from the plug, stripped it down and put a jumper lead with a round clip. I then picked one of the 2 pins on that plug that turned off and on with the key, placed the clip on it, pushed the plug back on. Now whenever my key is turned on, my pump works and when key is off, it goes off. Simple fix. |
