Check to see if you have coolant in cylinder #3 by taking out the plug and looking at the tip.

Try cleaning the throttle body by spraying a throttle cleaner into the throttle body.

Replace the fan relay switch. The dealer will charge you 400 to pull the bumper off, or you can buy the part for 45 and cut the hole in the plastic near the passenger headlight assembly and replace it yourself. There are instructions for this procedure on the web somewhere. I have had this problem more than once with my 02 GC V6.

I've not come across that particular symbol before, but anything showing a key is usually about the ignition systems.
Since it's not starting, my guess would be that your key isn't disarming the immobiliser.?
Have you got another key for that vehicle which you could try instead.?
Best of luck.

the lights began flashing intermittently on and off ???? . Wouldn't be a relay problem , a stuck relay the light's would be on all the time , wouldn't be able to shut them off . I would think a control module or secruity system . The BCM - body control module controls the lights . The Headlamp switch is a input to the BCM , the BCM does energize relays to turn on the lights . More then likely the automatic headlamp light sensor which is an input to the BCM could be the problem . Taking the vehicle to a qualified repair shop an having the BCM checked for DTC'S - diagnostic trouble codes is your best bet , Don't take it to autozone , advance etc... as they can not access these codes .

I don't understand what you mean this must be an automatic transmission what is first .
If so and the transmission fluid looks OK
First is drive dose the 4 wheel work
So you can't drive the vehicle in forward motion .
Neutral reverse and park at best can make go backwards .
The good news is it dosen't sound like the tranny is shot do you have other electrical problems or it also could be a linkage problem if cable or VACUUM operated .

Probably universal joints on the drive shafts needs replacing. The rubber boots split and water and grit gets in.

Got any phone charges or other electronics in the vehicle? Disconnect them and try the remote. Those can cause interference.

If you did the keyless entry programming thing and it doesn't work you need a new keyless entry module or maybe a fuse is blown...Check the fuses and go from there...

i didnt but can answer this one. they leak because the o rings in the filter adapter just plain get old. jeeps are famous for bad oil pressure switches and have been for years.hopefully you dont have a 99 or 2000 4.0 liter engine because chances are if you do you will suffer piston skirt failure at between 140,000 and 180,000 miles and will need a rebuild
