Bob is right,that old low pressure TBI system is cheap and easy to repair,the fuel pump will die quickly from the restriction and near 0 fuel flow of an idling or stopped engine with a carb. The pump will make considerably more pressure than a carb can handle without the pressure regulator(actually a relief/dump valve) to control the pressure buildup to 13 psi and allow a constant flow of fuel through the pump for cooling flow that returns to the fuel tank.
Add to that the computer problems with the ignition advance and transmission shifting caused by the computer reverting to the "limp home" mode when it senses that the injectors are not working.
