Engine cranks at normal speed but will not start Do steps A and B. during extreme cold weather. Do steps K through O. Engine cranks at normal speed but will not start after  two  attempts  to  start. Do  steps  C  through  J. Engine cranks slowly and will not start. Do  steps  P  through  S. A   Turn   MASTER   switch   on   and   test   batteries   in accordance   with   serviceability   test   in   Table   2-1 PMCS. B   While   moving   transmission   shift   lever   into   park position,   observe   neutral   safety   switch   activating lever.   If   lever   fails   to   move,   check   linkage connecting   transmission   shift   assembly   to   neutral safety   switch   lever   cross   shaft   (see   paragraph   9- 77).  Reconnect  linkage  if  disconnected.  If  linkage  is bent,  straighten  or  replace  damaged  parts.  If  lever does   not   depress   neutral   safety   switch,   make adjustments (see paragraph 9-77). 2 - 4 0 Change  1
