If you remove that Brown Hose at the Vacuum Shutoff on the Fuel Injection Pump and your Engine starts up and runs like it is supposed to; it would be an indication that the other Vacuum Valve that is attached to your Steering Wheel Lock behind the Dash needs replacing.

If after pulling the Brown Hose off your Engine still has the same problem it indicates that that Vacuum Valve attached to the Steering Wheel Lock has nothing to do with your problem.

UPDATE: the vacuum hose was not the problem. got my cleaned up, rebuilt, monark nozzle filled injectors back, all five for $167.00. put them in today with only one old heat shield giving me any problems. had to tear it up pretty good to get it out of there. all my old injectors were thick with black soot all over the nozzles and pretty cruddy and dirty too. new ones went in just fine. tomorrow morning is the real cold start test!
