Welcome to 2CarPros.
Honestly, I don't see how. They aren't connected in any way. You said you are getting a reading at the fuel pump. How many volts is present? Did you replace the fuel pump speed control relay (FPSC)?
I have attached three pictures. The first picture indicates where the fuel pump ground is located. Confirm it is clean, tight, undamaged, and not corroded.
Pictures 2 and 3 are related to the fuel pump speed control relay. That relay could be your issue. Check the relay. If there is another one with the same part number, switch them. Here is a link that explains how to test a relay:

Also, pictures 4 and 5 show the entire exterior lighting system for your vehicle. I highlighted the signal so you could find it easier. It has a different ground and honestly, I don't see how it could be related. I had to break the picture in half to include everything, but I did overlap them so you could follow.
Let me know about the relay. And believe it or not, the FPSC relay sends power to the pump based on need. One common symptom is not priming.
Let me know exactly what is going on. Is the pump working at all or just not priming?
Let me know.
