”With the key on” Do you have power to the #30 terminal of the relay socket?

Thanks DJ.

When I have the fuel pump hooked up straight to the battery with the car on I have power to every thing but when I plug the fuel pump into the stock wiring I don't get power to the fuel pump when I turn the key

This thread is from 2015. The poster you replied to has not been here since then so I don't think you'll get an answer.

If you're having problems, I suggest starting a new thread describing what symptoms you have and what you've already done.

and Welcome!
