• Do you mean throttle body? Service manual says Throttle Body Injection (TBI) The best way to check fuel pressure is with a fuel pressure gauge. On the tracker you need an adapter that connects the pressure gauge to the fuel filter inlet. You can visually look down the TB to see fuel spray. If you have none, it might be a broken wire to the injector. They sell a tester for fuel injectors, it's hard to see with a test light or volt meter because it's so fast. Good luck
