Your tps should not stop your car from starting. It is to tell the ecu the throttle position for fueling. An example is when your foot is planted it can supply the calculations to the ecu. Please correct me if im wrong. You can adjust the tps by undoing the 2 screws and turn it untill it clicks.If you turn it and it still wont click then use a junior hack saw and make the hole into endless slots. this will allow for further adjustmant. It worked on mine.
