Hello everyone. I am a 2 month owner of a 2001 TJ, and I love this thing. I am however having a couple of issues with it.

1. When it sits for more than a few minutes, it will not start on the first try, no matter how long you crank it. Stop cranking, hit the key again, and it fires right up. Any ideas??

2. As soon as I start the Jeep, the temp gauge goes right up to 210*. It never moves, no matter how much I drive. Any ideas??

3. It doesn't have factory fog lamps, but the fog lamp indicator is lit constantly on the instrument panel. Not a big deal, but I would like to correct it, and possibly hook my aftermarket lights to it.

4. My cruise control and horn do not work. I'm guessing clock spring, but could it be something simple?

I would appreciate any helpful tips I can get, before I dive into trying to fix some of these issues on my own.

I can address item #1 on your list. I had this same problem with my 2004 TJ, and it was resolved by replacing the fuel pump and fuel pressure regulator. The problem is the regulator which maintains pressure in the fuel line when the car is sitting and not running. When it sits, it loses pressure, but when you first try to start it, it build up pressure and then on the second try it is pressurized and will start right up.

Replacing the fuel pump is not a really difficult DIY project if you are willing to give it a try. The hardest part is that you need to drop the fuel tank since the pump is located in the top of the tank.

If the engine doesn't start in about three seconds, it isn't going to start on that start attempt no matter how long you crank. Reason is that the PCM shuts the injectors off after about two seconds of cranking to prevent flooding.

Check your horn relay first, it can swapped with ADS relay under the hood. As for the airbag, I would start with seeing if there are any codes set, it may be an impact sensor and not the clock spring. However both your horn and air bag run through the clock spring so most likely that is the issue.

2. Unplug the wire from the temp sensor (near the thermostat housing/upper radiator hose) & see if the gauge drops.



3. You may not have fog lights now but it may have originally had them. See if there is a relay in the spot labeled “fog lamp relay” in the PDC. If so, pull the relay & the indicator should go off.
