My Jeep wont start..Please help me!

I have an 05 Wrangler X, I warmed it up one morning and when I went out to leave it was dead. My heater was still blowing but the jeep wasn't running. I bought a computer...wasn't the problem. When you turn the key on it shows the mileage, but that's it. Got any suggestions?

Are the guages doing/showing anything?

Check the basics:

Fuel : There's a schrader valve located on the fuel rail you can test. It looks like a bycle tire valve. Turn the key to "on" to activate the fuel pump, open the cap and depress the needle to check for the presence of fuel. If you do not have any pressure, check the relay then the pump.

Air : You never usually have a clogged filter or intake but it helps to check.

Fire: Check the ignition relay and circuit.

I know it has gas, it does not crank at all. Where is the ignition relay and circuit located? When I turn the key all I hear is a click in the glove box area and there's a relay there. Um....the gauges don't work other than showing the mileage and then the gas light and check engine comes on a few seconds later. Thanks for helping!

Are you sure you have a good charge in the battery?

Okay My motto is cheapest and easiest first. Check your battery. Make sure that the connection is clean. Look for corrosion on the terminals and the connectors. Any amount of corrosion can cause your battery to drain. Clean the connections with a wire brush. You could have enough power to light a few guages, but not enough to get the fuel pump going or start your jeep. If you have another vehicle at your disposal, swap the batteries and see if it cranks. Take your battery to any auto parts store and have them test it. When you replace it make sure that the connection is good and tight. You should not be able to move the cables at all if it is. My 06 did pretty much the same thing and it was the battery.

Yep...good battery. The click in the glove box won't click until the check engine light comes on.

So you get an engine light but you can't retrieve the code. How are you trying to get the code?

Are we talking a test light or a code reader?

That makes no sense.... You have an engine code but cannot retrieve it.

Are you sure you connected everything back up properly? It sounds like yo have an electrical problem. Are you absolutley sure the battery is fully charged?

Yep, the battery is fully charged. Looked at wires under the dash, steering, and the glove box....the only thing it does is that clicking noise and that dinging noise when the you first put the key in. The mileage comes on then the fuel light comes on then the engine light comes on...then it will click, but it don't click until the engine light comes on. Crazy..I gotta get it fixed tho! Love my Jeep!

Check the ignition relay. It's located on the inside fender on the passenger side.

The cel will come on everytime the key is turned. It does not mean that it is throwing a code.

He switch the relays around, switch the horn relay to the starter one and it didn't do anything. But the horn works....I am so confused!! Any more thoughts on this?

Back to basics -
Does it crank when you try? You said it didn't.

If it won't crank, it's not getting enough power for anything.

Try it, if it doesn't, - right on the starter, jumper the small wire to the battery cable - crank now?
