The majority of vehicles works like this: if there is no spark there is no fuel injection and if you have spark the only reasons why there is no injection is because the module of ignition (igniter) this defective and is not sending the confirmation signal of spark to the ECU, that some cut cable or that the computer is defective. Check the module and connections if you have how to get codes better to help you in your diagnosis check the battery and ignition voltages of the ECU and the reference voltage in the MAP, TPS and COOLANT sensors this is 5V if everything is well tried with another module first and after all the tests with another ECU.
