You mean "it is not telling the injectors to fire". BTW the "Engine Computer" is called the Engine Control Module (ECM) by GM. BTW the ICM (Ignition Contol Module) sends an RPM based signals to the ECM telling the injectors when to fire. The length of time the injectors fire (pulse width modulation) is determined by other sensors like the MAF (Mass Air Flow Meter). Does the tach jump when the injectors stop ? ED01 is the throttle position sensor (TPS) - if the TPS drops to zero the engine will stall, ED06 is the injector pulse width. Is either jumping around when the engine falters ? There is no substitute for proper information. Otherwise you are just throwing parts and money at it.
