Can someone show me a diagram of where the ignition timing marks are on the engine block for a 99 dodge ram 3.9L if there are any marks? Any help is appreciated

 

Nope. No marks. Ignition timing is controlled by the computer via the cranks sensor signal. With number once cylinder at TDC, the distributor rotor should be pointing at the notch in the distributor body. Which should be roughly facing towards the number 2 cylinder. (toward the passenger side front.) That should be close enough for it to start and run, but, need to set fuel sync, and you need a good scanner for that.
