if the turbo is not working or the vacume boost pressure pipe is not connected to the turbo or the top of the fuel pump you will have no power to check the turbo rev the engine to 4000 rpm and at the same time try to squeeze rubber pipe going into the inlet manifold if it goes hard you have turbo pressure and the turbo is working but if your able to squeeze it almost half it not working.so if you have that pressure check that you have a vacume pipe coming from either the inlet manifold or the turbo to the top of the injector pump or to a boost pressure
