1990 V3500 TBI problems

[1990v3500]

Just picked up a really clean 1990 v3500 4X4 with 454, th400, np205, 14 bolt, Dana 60. Was running great. Got it home, crawled underneath and wires were scattered all over going to the gas tanks. I got the schematic of the factory wiring, removed all the rat nest and re wired all. I now have a good selector valve and good pressure to the TBI, but no vroom vroom. I teased it with gas down the intake and it started. Had a friend try and start it and I observed no fuel coming from the injectors. I replaced the filter and rebuilt the TBI with new screens and o rings. Still no fuel. I jumped the injectors with a battery and they click. I have power at the injector connector with the key on, but no ground. Can someone please help me???
