F'n double post...sorry
My jeep just start to start hard. It use to pop right out but now it takes a few seconds of it turning over to start. Its an 04 LJ with just about 48k on it. I'm thinking it might be my fuel filter starting to get junk in it. I was going to rum a fuel system treatment through it on my next tank of gas but not sure if it will help. What do you guys think

Semper Fi
Little Red 1986 CJ-7
7,000 mi and counting on the TBI 258
DUI, Np435, Twin Sticked D300, Locked Waggy D44s
4" SUA with homebrew spring outboard
37" siped swampers with some other nifty bolt-ons.
I've never been a fan of additives, I think it's snake oil and covers up problems or makes them worse. Run some Premium in there for a tank and run that bitch till empty and repeat. Then change your filter.
Coming up on 50K miles, mighty check/clean/change spark plugs as well

I would do as said above. check and clean all grounds as well. A weak ground will cause your exact symptom.
Not sure about the newer rigs like your '04, but in the XJ's and TJ's (late '90's early '00's) they had problems with the in tank fuel pumps.
Either the pump, or the built in check valve, will go out.
To see if that's it, cycle the key 2-3 times before starting it.
(turn the key all the way on without actually cranking, then off, then on, then crank on the 3rd time)
If it is the check valve, doing this will get enough fuel/pressure to the rail, so it will start right away.
Fuel pumps aren't cheap, so a lot of guys will just 'cycle' the ignition, until it fails completely(if it's just the check valve, this won't hurt anything)
As long as the people remain armed,
government knows that it cannot rule over the people by force.
Those who stand in defiance of unconstitutional laws
do so out of duty, honor, oath and love of country.
"Certified Jeep Junky!"
Exactly what hillbilly said as well. It was on the tip of my tongue. Just turn the key all the way with out starting a couple times. You should be able to hear the fuel pump kick on.
Check to see if it has a crankshaft position sensor, on XJ's they are located on the driverside of the bell housing, dont know if LJ's have em
Time for a spark plug change. Your Jeep does not have a replaceable fuel filter. Mopar did away with those quite a few years back. I have an '05 that was doing the same thing. Put plugs in it (that's the only tune up part anymore) and it fixed it. Any "check engine" lights?
I'm Mike, make sure you spell it right, because I do not want to get the wrong A$$hole in trouble.
If you do not have time to do it right the first time, how do you have time do do it over?

Go to any auto parts website and look up a fuel filter for any late model Jeep. Mopar stopped using fuel filters on some models starting back in 1994 and Jeep stopped putting them on Wranglers in the early 2000s. No Liberty, Commander, Compass, or Patriot ever had one (gas only). Not counting the 5 years I served (I didn't join until I was 31), I've been selling auto parts and swinging wrenches for over 13 years professionally. I stand by my statement and wouldn't give advice that wasn't true or that I couldn't back up. The Grands did continue to use fuel filters (they are the only one), but his vehicle is a Wrangler which is what I was referring to in my previous post.![]()
