I checked all fuses wires and distibutor position. I also changed the ingniton module(next to coil) and the other ignition component in the distributor assy.

I have checked those items. The distributor has power to it but the coil does not. there is fuel pressure but the injectors are not working. I have tested the crank sensor, ignition module, cap, rotor, wires plugs and fuses many times each.

This is a S&T series and I am starting to question the VCM.

But, the truck ran when I brought it in the garage. I changed the lower intake gasket. The repair went smooth and I followed standard procedure for such a task.

When you say the coil does not-do you meant 2ndary spark or battery voltage to the ignition coil -positive terminal?

As I crank the engine over the tach does not move at all, I don't know if that helps at all.
