I hope this is the right place to post this

I just swaped a 94 6.5 turbo diesel to a 94 454 tbi. I have changed the pcm engine harness were puled from a suburban. did not change the dash harness that is tied into the fuse box and a big plug on the bottom of the firewall on the driver side I have also not changed the ignition switch yet and I do not know if I have to change it or the harness. my problem is I can connect the coil and fuel pump to the battery and the truck will not start unless I spray it with starting fluid and when I stop spraying it dies. if I do not connect the coil directly to the battery I have no spark. under all conditions I also have no injector pulse I also need to know how to connect the fuel pump to the relay.
