The rack that is to control the injection amount of the fuel injection pump does not have sufficient strength around the notches. Also, the way the fuel injection pump is attached to the engine is not appropriate. For these reasons, the rack can break from continued high revs, in which case the engine revs could rise and at worst this could result in a fire. Note: This problem was reported in RJ-1241-0, submitted on 22nd September 2004, but the vehicles to be recalled were not fully accounted for, so this recall is to add some vehicles to the recall list.
