Check the injector pulses with an osciliscope. If you arent getting a pulse check the ecu. I have cooked 2 of them. One killed my ignition but had good fuel. the second time it wouldnt open the injectors but had good spark. A quick check is to take the ecu out and take the cover off. then look for burnt electrical components.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

I'd suspect a sticking injector--car should have set the check engine light. Read the code(s) to progress further. If the coil pack were a problem, it would not be likely to fix itself. If the codes indicate an injector problem, try an injector cleaner in the fuel--worst case, replace the bad injector. The codes should indicate which cylinder to change the injector.
