May need to rebuild the fuel regulator in the TBI. They make kits to do that.

Thanks for you response. .i will put it on my list..just to mention the new fule pump was really loud never heard a pump that loud do you think it could be a defect..thanks again...

Was it under gas? Always keep it under gas, no less than a 1/4 tank of gas. The gas keeps it from burning out and dampens the sound...keeps it cool. So no I wouldn't know if it is defective. Maybe check the fuel pressure with it.

Ok .i had a half a tank ill fill it up..thanks again...
