4.3 liter engine. throttle body not working...its a 1988 not a 1990

I assume when you say that the throttle body doesn't work you mean it doesn't start. It would be very helpful if you could tell us what size engine you have.

1990 gmc sonoma 4.3 ,gas goes into the tbi, but doesn't come out.still engine doesn't start. what's wrong with it? please answer.

change the tps (throttle posicion sensor) that will fix it..
