Default Bad Injector Driver?

Well guys just got the truck started today and had a few problems, Cylinders #2,4,6,8 are not gettin any gas at all but spark plugs are firing... Put a bulb in the injector plugs to check for power from my vcm and it was lighting on all the injector plugs but not dropping any gas into the cylinder.....1,3,5,7 all firing fine so we swapped injectors from one side to the other as a last resort and still the samn problem.... Anyone else ran into this before? The only thing left could be the harness or the vcm is what we belive, all injectors are brand new 92# Dekas and fuel pressure is @ 60 psi.... Any help will be appreciated thanks

My son done the same thing awhile back. Ended up blowing the 90mm Fast Intake to pieces, once it finally fired alittle. I guess all that fuel vapors built up in the intake.
I like to have never found the problem. I started labeling all the coil pack and injector wires.
Glad you found it before it mess something else up.

You mean the coil connectors were plugged into the wrong coils...?

If so, how would that stop bank 2 injectors from firing...?

I guess I missed something. How can you plug them in backwards? Picture anyone?
