re somewhat the same problem
I have looked over this post and my problem is somewhat close, my fuel pump is not coming on at all, i ram a jumper wire at the relay under the seat and it did come on, I found the fuselink on the blue wire under the hood was blown, I replaced the fuselink with an inline 25 amp fuse, each time I turn the switch over it blows the 25 amp fuse leading me to believe that the blue wire (which turns into a yellow wire and runs to the EEC computer at the passenger side kick panel has a short or ground, when i test the block 22 port i come up with no power. Any ideas or suggestions???????
