Hey scotty, i have a 1997 jeep wrangler 2.5L , and im having a problem trying to start it up. It will crank and continue to cranks, i tried putting starter fluid in the intake, but it didnt do much, but sounding like it wanted to start but just went to cranking. I did by a new battery for it, so i know its not the battery, i also bought new spark plugs and spark plug wires thinking it was that. But even then it still doesnt do nothing but crank. I do hear my fuel pump priming but the thing is when i turn my key, my fuel pump never stops making a humming noise like it's pushing fuel but it never stops making that noise.

Might have an idea on what it might be?

those are notorious for blowing a head gasket, but do try these video fixes first https://www.youtube.com/watch?v=064Ilsz8Fzg
