Blown fuse; open/shorted wire; ignition switch not turning on Main Relay

If you don't have voltage at the injectors, then you probably don't have it at the ECU or IACV too as all these components are fed battery voltage through the Main Relay. The Main Relay gets its signal from the ignition switch.

So when you turn the key on, you don't get the CEL on for 2 seconds while the fuel pump primes too, correct?

So then - the injectors aren't getting +12v or they aren't getting a ground signal?

If they aren't getting +12v, but your fuel pump is priming, then start tracing the feed wire from the Main Relay to the junction connector that feeds the ECU, injectors and IACV.

Did you install a resistor box, by chance?

yep install a resistor box, what i did was i got a multimeteter turned the car to the on posistion pulled a injector connector clip put the positive to the yellow black wire and the negative to the negative on the battery and got no voltage.

What about the voltage going INTO the resistor box? The resistor box feeds the injectors so just start back tracing through the wiring until you find where voltage stopped.

Not really knowing about the cap (though a possibility as the cap could be what makes it a 'junction' connector) - but do you at least have +12v going to one wire in that connector?

If you have a helms manual there is a trouble shoot that you can followed to find out what is wrong.

As for myself, I had a problem similar to yours a couple of months ago in my integra after I swapped out some 450s and popped in the stockers. It ran great for a couple of days then the check engine light came on and after trouble shooting I found out I wan't getting any voltage to one of the injectors. I had to replace my ecu, and problem fixed.

Yeah, it's not just a "cap", in fact it's not really a connector at all... it is a bus block (power distribution terminal.) The cap is what transfers the 12V from the input wire to all the other wires.
