electronic engine control unit calculates the mass of fuel to inject, not how wide it sprays. It's the type of solenoid that you use. Some have wider spray nzzles than others. An external Fuel pump helps the delivery of the fuel. Also since fuel injectors rely on mass air flows nowadays, you have to have proper mixture coming through. hows your Fuel pressure regulator?
The throttle position sensor reports to the computer the position of the throttle butterfly valve, which the ECM uses to calculate the load upon the engine-but inorder for this to run, you may need an external pump.
Sounds like nothing is being grounded back to the ECM to even give a reading. If your regulator is improper and you do not have a external pump (depending on your model), than check those. If not, Start from scratch.

SOURCE: Flat spot around 2000r/m
Try accelerating at different speeds, for example push pedal further down, or ease into it real slow & let it climb, and see if it still dies at 2000 rpm, just to see if pedal position makes any difference to see if maybe TP sensor has bad spot.

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up
