Okay sorry before hand I basically have no knowledge of motors at all. If my timing belt would have broken would I have seen it? Cuz I looked at all of my belts and they all seem to be there. Is it possible for it to have jumped timing somehow?

I had the distributor cap off and had someone start it and it's not turning at all

It's a 98 and I haven't been listening I'll listen for that when I try to start it up next.

Okay so from the beginning when I originally bought the truck (around 2 and a half months) it was fine. Saw a slow leak of oil and changed the oil and filter(it wasn't screwed in all the way or something) and I was driving it down the highway doing probably 70 and it backfired and shut off completely. Now every time I start it, it tries to turn over but won't fire over completely I have no idea what to do as I have never had a problem with something just not starting and don't know where to look
