Engine cranking, do you have spark at the plugs? Engine cranking, you have voltage to injectors but, no ground pulse? The computer grounds the injector circuit. Maybe the computer doesn't see an rpm signal?

The info I looked at was F-series 6 cylinder. The autozone site has free wiring diagrams, you have to register, but, it is free. Once you register click on repair info, I believe the wiring diagrams are under the chassis link.
