I converted a Nissan pickup from gas to diesel for a friend and the used TD23 engine he purchased from Japan that came in Terrano's and other trucks not sold in the USA has stuck injectors. I can see the pintle on 2 of them stuck up in the injector so it needs a minimum of 2 injectors but I will put all 4 in if I can find a place that sells them. Anyone have any ideas? Someone told me that the TD27 in forklifts are exactly the same engine with just a little more displacement.
