Problem on the vacuum switch located on intake manifold (driver side near vacuum tank hose fitting): the switch is shot or missing or not correctly wired: 2 wires, one (yellow) coming from starter relay ("ign" post) and the other (brown) which goes to neutral switch on trans. You could test the switch if you remove it, apply some "vacuum" (i tried with .. mouth and it's work ..) ; put an ohmeter on the posts: with no vacuum the 2 posts are shortened, with vacuum switch is open. -- Philippe COURANT (Pau, France) Imperial 57 Crown convertible Buick 58 Roadmaster sedan - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
