I have no power at the pump.

I have 12.4 volts at pin #13 on the relay board.

No power at pin #5 or 7, old eyes can't see the stripe colors very well.

Fuses are good.

Am I missing something?

Thanks in advance.

After cleaning some corrosion around pin13 and 14, I think I have come to the final problem.

I have power to pin #14, through the relay and the fuse.

There is 0 resistance between pin 13 plug and and the fuel pump. There is 0 voltage to the pump when the plug is installed over pin 13.

Looks Like I'm not getting power from the board to the pin 13 plug??

Is there a solution, am I missing something?

thanks,
