RECENTLY MY 99 W163 STARTED HAVING PROBLEMS CRANKING WHEN ITS WARMED UP. I USED TO BE ABLE TO TAKE IT OUT OF PARK AND PUT IT BACK INTO PARK AND THEN IT WOULD START. BUT AS ITS BECOME SOMETHING THAT IS HAPPENING MORE OFTEN, THIS “FIX” ISN'T HELPING. THIS ALSO LEADS ME TO BELIEVE IT ISN'T AN ISSUE WITH MY STARTER. IM ABOUT TO CHECK MY CONNECTIONS IN THE RELAY BOX, CHECK MY CONNECTIONS AND GROUNDS, AND MY FUSE BOX. I HAVE FOUND SOMNE ELECTRICAL SCHEMATICS ELSEWHERE IN THE FORUM, BUT ANY HELP AND/OR ADVICE WOULD BE APPRECIATED REGARDING THE PATH MY DIAGNOSTICS SHOULD FOL;LOW.
