I have a 1986 f250 6.9 diesel. I have replaced the injector cups and o rings and lines as well as purged my lines for air and I still can't get the old girl to start. I am looking for any and all help

 

Have you checked the glow plugs for proper operation? Mine doesn't like to start even in 70 degree weather without them.

For much more info, check out the Pre-Powerstroke forum, there is plenty of knowledgeable and helpful folks there.

 

Yea they are good
