The TPS(Throttle opening) sends signal to ECM ,then ECM sends a pulse signal to fire the injectors for exact amount of fuel to be injected.( Just the basic format) There should be a fuel regulator some where near the fuel rail, need to find the exact fuel PSI required and test yours. Need to see if the injectors are getting a fire pulse command from the ECM.
