Can fuel pump fuse cause 2 Solenoid PO Codes?

What is your question?

My engine light was on in my 1997 dodge ram 1500 v8 magnum, since I got it a month ago. I had several PO Codes and changed the O2 sensor and all I had left was 2 Solenoid codes. Tonight I checked fuses because my radio shuts as soon as I turn on the car and I saw that the fuel pump fuel (i believe) was missing and another was loose. I switched the 40A fuse from the trailer lights to the missing one and now the engine light is off and there are no PO Codes. Is this possible?? I feel like a fool for not checking this sooner but I am the furthest thing from a mechanic and just learning. I admit I love it and excited to learn more. Thanks for your help.
