Jeep won't start

The only thing that comes to mind is a clogged fuel filter. Happened to me before and the fuel filter was the last thing I checked. Note: they tend to be hidden along the fuel line somewhere.

Just a couple of questions: Whats not working, fuel or spark? Or are both not working now? What happened when it quit working? What made you decide to replace everything you did? This might point me in the right direction to see if I can help.

Fuel filter is new...fuel pump had bad pressure & replaced. When it stopped running it was misfiring, pulled over & shut it off and it wouldn't restart. Went through forums that said bad cam shaft or ignition coil. It cranks but has no spark.

Wow that's the right question, why replace that many parts. Codes, did you check to see what if any were stored before part change began? You may have others now but maybe the original is in there.
