1998 fuel filter...Where is it?
Where in the blazes is the fuel filter on a 1998 4.0 Cherokee? On my Grand Cherokee, it is just a foot or so away from the gas tank in line... Also, is there a way to test the fuel pump? I don't hear it prime/start when I turn on the key and there is NO fuel at the fuel rail at all..
Thanks...

When my Jeep stops making strange noises, I become concerned. That usually means I have to go back and find whatever fell off.

1997-2001 the fuel filter is inside the gas tank and is not routinely serviced unless you are experiencing fuel delivery issues.
Apply 12 volts directly to the fuel pump to test it.
What symptoms are you experiencing? There are some common Cherokee sensor failures that result in a no-start situation or the fuel pump not running.

No fuel at all coming to the fuel rail.... I cannot hear the fuel pump noise when it activates when you turn on the key. How do I apply 12 volts to the fuel pump without blowing myself up??

It sounds like you may either have a blown fuse, bad relay or fuel pump. Check the fuse and relay and then start to diagnose the pump..

Honestly I beleive the relay should be there on the 96, but I own a 98 so i am not 100%. Do you haveyour owners manual, there is a fuse diagram for your Jeep in there.. and yeah the fuses should be in the kick panel.

Can I disconnect the clip underneath about a foot from the fuel tank and jump it to see if the pump comes to life?? Thanks a lot for the fuse diagrams...

All you have to do is test the lead going to the tank to make sure it has juice. You are going to need an ohmeter to do this.

Have someone turn the key like they are trying to start it take a rubber mallet and tap on gas tank kinda same way you do with a starter.

It looks like (not 100% sure yet) that no power is going to the fuel pump... the gas gauge stays down to the left and won't move.. CAN a bad crank position sensor cause the fuel pump NOT to work???
