I think it's because of the fuel filter but I hear that those are in the fuel tank and I can't fix it myself... Is that true? What else should I check besides the battery to find out what is wrong with my jeep?

My 97 6 cylinder Wrangler won't start. I turn the key and there's nothing - no clicks, no sound at all. The headlights will turn on as will the inside dome light but no gauge readings will appear. This just happened out of the blue. Checked battery - fine. Checked starter - fine. Checked fuses - fine. A couple wires going into the main fuse box under the hood have some corrossion but could this really be the problem?? Trying to check the ignition switch currently but can;t get the damn casing around the steering column removed as the black switch is bigger than the opening in the casing/paneling around the column.

If the engine turns over then your battery is good. And yes the fuel pump is in the fuel tank. You will need to drain as much fuel as you can from the tank. Then remove the filler line to the tank and then drop the tank to the ground and remove the ring at the top of the tank to remove the fuel pump.This is a very common problem with the jeeps.

It has No external filter, the filter is built into the fuel pump module inside the fuel tank, it is not changed unless the pump is replaced This is true of almost all makes and models now.
Overtime, JeepGrandCherokee fuel tanks develop rust and accumulate sediment. This is especially true if the tank sits empty for a period of time. Rust and sediment can break loose and cause clogged filters. When the filter is clogged, the engine does not receive the amount of fuel required to operate. The fuel tank can be cleaned out; however, replacing the tank is easier.
1 Apply the parking brake.
2 Remove the gas cap.
3 Remove the fuel pump relay from the power distribution center under the hood. Look at the underside of the power distribution cover, and locate the fuel pump relay.
4 Attempt to start the engine, cranking the engine for several seconds.
5 Turn the ignition to "Off." Install the fuel pump relay.
6 Disconnect the negative cable from the battery.
7 Lift the fuel tank into position, using the jack.
8 Attach the fuel filler hose and vapor return hose to the fuel tank.Tighten the clamps with a Phillips screwdriver.
9 Pivot the fuel tank retaining straps into position. Tighten the fuel tank retaining strap nuts with a socket and ratchet. Lower the jack.
10 Connect the fuel pump electrical connector, the fuel filter line and the fuel return line. Push the fuel line retainer into the chassis.
11 Raise the heat shield. Install the mounting bolts. Tighten the mounting bolts with a socket and ratchet.
12 Install the tow hooks or trailer hitch, if equipped.
13 Lift the skid plate into position with the jack. Tighten the skid plate mounting bolts with a socket and ratchet.
14 Attach the electrical service connector to the bumper with a socket and ratchet.
15 Raise the jack and remove the jack stands. Slowly, lower the vehicle.
16 Pour the fuel into the gas tank. Connect the negative battery cable.
If you haven't replaced the fuel filter in the last year or so, do it now-basic maintenance.
Check if the pump is working by turning key to ON (not crank), and listen for the pump in the tank to come on for a couple of seconds. Should hear a short hum or buzz verifying tank is working. If you don't hear it come on, either the pump is bad, or power is not reaching it. May have to pull the pump connector off at tank, and check for 12 volts on pump wire when someone cranks the car. If power there, the pump must be bad. If no power there at pump, check fuses for pump and fuel pump relay.
filter ? or the new fuel eats the line off the pump in the tank. if you hear the pump in the taank running there is a good chance it's the pump lines in the tank. there might be a access door under the seat or trunk that will allow you to service it without removing the tank = no fun.. some dodge vehicles the only filter they have is in the tank ! krazy !!
Check for pressure at your fuel rail, If your fuel pump is working correctly you should be getting fuel spraying out of the rail when you press in on the needle valve (sometimes covered by a small cap)
This will let you know if your fuel pump is working, and at least if fuel is making it past your filter.
dont go replacing everything...thats gonna get expensive real quick...especially that fuel pump. yep...the pump is inside the tank. stand out side your truck,and turn the key over,but not enough to start it. you should haer a whirring sound lasting about 2-3 secs. come from the back of the truck. this is the fuel pump powering up. if you dont hear it...then the pump is bad. if you do hear it, have a friend turn the key while you look at the carb/injectors to see if fuel is spraying thruthem,if it isnt....then you have a clogged fuel filter. BUT...b4 you do any of this...check your fuel pump relay and fuse to make sure they are good. a 10 cent fuse beats a 200 dollar pump any day.
keep me posted!!
If you put a fuel cleaner additive in the tank I would change the fuel filter. I believe on this model it is located in the frame just ahead of the fuel tank on the drivers side. Any foreign material cut loose from inside the tank from the cleaner often clogs the filter.
can you hear the fuel pump kick on when you turn key?(have an assitant turn key and listen for a buzz near the fuel tank) i think you have to take the fuel tank out to fix it.
If you removed water from filter it's a good bet you have water in the tank. Fuel system is self-purging. once connected, it should start. If you hear the pump running with key on, remove filter and dump it's contents into a glass jar & check for water. If any, drop tank and remove water!
try the fuel filter and make sure you have proper oil pressure!! Remeber if you have tried craking to many bad times then the plugs are going to be fouled out!! Means that they are going to be drowned with gas and need replacing!! Also make sure your fuel pump is coming on!! You should hear a hissin or a hummin noise back from the fuel tank!
I don't need help anymore... I took it to a mechanic and he fixed it. There was no way that I could have done it myself... Thanks.

need more info does it crank? does it sound like it wants to start? is there gas in it? ect..
When you say "my jeep won't start" that's pretty general. Please provide more detail.
Like:
Does it crank when you turn the key? ie does it turn over but won't start
Has anything unusual happened lately with the jeep that would affect starting?
Did this just happen one day, and before, it always started?
Better to have too much info than not enough.

what motor do you have and are you sure you have spark
