I havent yet, I was thinking about checking that next. Is it possible the relay has gone bad again?

It's possible. If it has, then it means there is something wrong and its blowing the relay. Or the relay is a defect.

Pulled the front sending unit to find out if the fuel pump was still working and it indeed Is still working. However, I used the test light to find out if I was getting power to the sending unit and still nothing. I started as far up as I could and found out that after the power comes out of the switch for the dual tanks, it ends somewhere shortly after. I ran a wire straight from the switch to the pump and it turned on. Went to start it, now that I had fuel flow and it started and then stopped again just like before. I have been told the computer has a possibility of being bad. Can somebody agree with that statement or is it something else?
