I owned one of those sorry diesels. Olds Delta 88 sedan, not sure of the year anymore. The previous owner buggered the dash so bad you had to go through a Batman style routine to start it. It did not work the normal way through the ignition switch. Turn key to ON position, flip glow plug toggle, flip fuel pump toggle, turn key to crank engine, and when started flip glow plug toggle to OFF. Woe be to the person who would forget that sequence. Of course no one could steal the car, and believe me they tried.
