My 1987 Grand National runs but the engine will not shift and the turbo will not kick in. I have a computer chip with 7 sittings and none are working now except 0 which turns the engine off.

Is the transmission a manual or at auto? I would assume it is an automatic. This may just be an issue with the fluid levels or the fluid is dirty and needs replacement. It could also be caused by a dirty transmission valve. If the debris is on the first gear valve then you may not be able to run it. If it is on the 2nd valve, then you may only get the first gear. Check for vacuum leaks on the exhaust for the turbo. It would be best to have the boost gauge used on this. Check your wiring, they may be loose or bad wiring due to heat or vibration.
