Sometimes Cranks but won't start for no apparent reason

Can you copy and paste a video link on how to read the flash codes if I post it?

On a lot of older Dodge product's you can rotate the ignition key on and off 3 times and the light will start flashing codes at you. Try that and look for long and short pauses with a longer break in between. Watch it several time's and you'll figure it out. You will mainly be looking for a CAMSHAFT sensor code at this point. Exp. ____ _ _ is 12, ___ ___ ___ ___ ___ _ _ _ _ _ is 55. 12 is a normal start code and 55 is the normal finished code. ___ ___ _ _ _ is 23 I'm sure you get the idea.
