Fuel Issues

Hi all, I've been researching on here trying to find the source of my problem. I have been chasing fuel issues for about 2 weeks now. I have a 1987 V30, 454 TBI, SM465.

I was drive around all fine, started and stopped at different places multiple times during the day. At night i went to start my truck to go home and it started and then died 3 seconds later. It would not restart at all. It was late so I left it til the morning. I noticed my fuel slector switch must of got knocked and it was in the middle, so i moved it back to the right side tank (no left tank installed) and still wouldnt fire. It would run on starting fluid though so i know its fuel related. Started checking things, tracing them down, changed the fuel relay, getting power through that now. Thought it was the fuel pump since i couldnt hear it running, changed that and then i started getting 0 volts on the wire to the pump (i had power before i decided to replace the pump). Went back and tested my old pump and it worked so now I know there is some other issue. Well I jumpered out the switch and connected the Tan/white wire to the gray wire and now my fuel pump will run and pump fuel. I thought, great, now it will start. No dice! Still is not getting any fuel through the TBI. I checked and tested all the fuses under the dash and they are all good. I cant seem to figure out why my injectors will not fire. I cannot smell any fuel when the pump primes or the engine is turning over. The fuel pump is definately running though during those operations.

I have been trying to trace down what it can be and cannot figure out why my injectors will not fire!?! Anyone have any clue? This is my first square body and i am reading and learning but I am stumped right now. Also after replacing the fuel pump, my fuel gauge is now max way passed full. I assume this is a ground issue somewhere and not sure if that would effect my truck not starting?

Sorry for the long post, and thanks in advance for your help!
