92 LT5 ecu ignition program and control

Just a bit confused now . Im unsure if you mean I cant use the stock ecu to run just timing and ignition control when Ive no sensors for fueling returning signals to the ecm .
Basic question is if I removed all injector wiring and map sensors ,TPS, 02 sensors, coolant temp etc etc but left ignition sensors like crank sensor and knock sensor would the ecm still carry out the ignition function when over the 400rpm ?
