A nice fellow member suggested that replacing fuse #5 is the fix.

Diesel 300, yes, I can turn the key all the way and no starter engagement or anything.
I am going to replace fuse #5 and also if it does it again in another blue moon, I will try keeping the key on start and moving the shifter.

Thanks

But it continues to work fine now.
No hesitation in starting. Shifter bushings were all replaced some 7 months ago during the trans rebuild.
