More fuel pump problems, help????? Options

[mxdude914]

I finally thought i had the fuel pump problem worked out but i was wrong. I traced it back to starting when i reconnected the brakelight wire that the p/o had cut, when i connected it, the brake light fuse would blow. I messed with it for a while and found that if i just cut the back up light wire the problem was solved. This is when the fuel pump started cutting out, then i thought it was fixed when it did it again, actually a few times after it warms up, then i just take the main relay out and put it back in and it will sometimes run for a minute or two. Sometimes it wont start back up unless i use a diff. relay. Does anyone have any explanations?

are your taillights wired correct, i mean they work etc correct? Trace your taillight wires back to the board and see if there has been any tampering or splicing up there. Is your fuel pump in the front or rear? Could someone have ran a new wire and relocated the pump as ive seen before? Check your grounds! ok thats all i have.
