As the Timing Chain elongates/stretches your Fuel Injection Pump Timing becomes late/retarded.

If you use the Timing/Locking Pin I suggest putting a Note on your Steering Wheel so you don’t start the Engine with the Pin in place.

If you have the Timing/Locking Pin you could rotate the Engine till it is coming up on the Compression stroke and continue past top dead center to the proper After Top Dead Center timing degrees (one of the under the Hood Emission Stickers on your Car should have that info for your specific year and model).

Remove the Plug where the Timing/Locking Pin would go and loosen the Fuel Injection Pump Nuts or Blots where it bolts to the Engine and also the rear support bracket Nut/Bolt.

Insert the Timing Locking Pin so that the groove in the Pin end of it is Horizontal after it is screwed all the way in.

Since the Timing Chain stretch retards the timing a slight rotation of the top of your Fuel Injection Pump towards the Engine Block should cause the Pump to lock to the Timing/Locking Pin.

Tighten up the all of the Nuts or Bolts that Hold the Fuel Injection Pump down and remove the Timing Locking Pin and replace the Plug and you are don.
