Hi, Do you have a RED LED on the left side of the cluster either ON all the time as soon as ignition is turned ON? The earlier KJs do not have this red LED but instead has an amber ""Key"icon with a stripe through..same applies..is it ON or Flashing. This is for the SKIS anti-theft system so first try another chipped key...assuming you have SKIS installed! Do you have the ëngine"icon lit ie. pointing to some engine problem.

You need to hear if your fuel pump starts to run at the rear as soon as ignition is turned ON otherwise you get no fuel up front to the motor...once again check all fuses.If the fuel pump is not running and fuses are OK....remove the Fuel Pump Relay from the box under the hood. Locate the female pins 30 and 87 inside the empty relay socket and jumper t em together with a piece of wire,,,if pump now runs try starting the motor.

If you do not come right get back to me and I will advise you further!

Hi, You need to join this forum and post your problem so that all members can come up with suggestions. I have never heard of an IOD fuse....check all the fuses in the box under the hood and the fuse panel inside the cabin.
You need to get the stored codes read out, try the "key" trick. Turn the ignition ON/OFF rapidly 4 times. After the 4th time leave the ignition ON. The Odometer display should read out the stored codes from the oldest...which may no longer be valid...to the latest. Otherwise a common problem is the Crankshaft Sensor or the Camshaft sensor....only replace with genuine OEM parts! You can download the Jeep KJ Service Manual here...includes the codes and the circuit diagrams. The 2004 version is not listed but the 2003 KJ Service Manual should be close enough. Also try jeepforum.com and lostjeeps.com.

Hi,
you were recommended as a good source in one of the electronics posts. I had some issues with a head unit installation and had a blown fuse that impacted the power locks, interior lights, and gauges. I replaced the fuse and all came back on and seemed to work OK, but now car won't start. It's getting plenty of juice and cranks but won't catch. several forums on web suggested IOD fuse. funny thing is I cannot find any good information on where it's located on a 2004 Liberty. Plenty of detailed pics for other Jeep models but nothing on Liberty. Can you help me? Also, any other thoughts you have on other potential solutions would be much appreciated.

thanks for your time/expertise,
