I have a 1999 Jeep G C Limited 4.7 4x4 I drove my Jeep last night with no problems and shut it off. Today, when I tried to start it, the battery was dead and I only got a clicking sound. I had a neighbor give me a jump. The Jeep tried to start right away but then failed. After that, the engine would only spin with the starter and it would not even hit on any cylinder. The fuel pump seems to be working when I turn on the key. I have checked all of the fuses that are related to the ignition and starting system. Now, the battery is dead and I have no way of checking it again until morning but want to try and diagnose my problem. Also, the headlights will not turn on from the steering column although all other lights will work with the juice left in the battery. Please advise???
Sounds like you have a bad alternator. Not recirculating juice back to the battery.

The door security has nothing to do with the jeep no starting. Check your electrical leads and also terminal leads that run to the battery. If you can, get your battery and your alternator tested to see if theyre any good. If your dash indicates the following while driving;" Transmission Overheat", then, with the engine running, check your transmission fluid level. If the transmission dipstick indaictes that the amount of fluid is low add maybe a quart to it. if you do this again and you find thats its doing the same thing, then there might be a couple of things wrong;
- 1. You may have a leak somewhere. Check your lines and check around the transmission pan. If you find a leak around the pan, than that means that you need a transmission filter kit. This includes a pan gasket and filter.
- 2. If you lift the hood and look over to the left (standing at the front of the car) and find the reserve tank to have a dark color liquid in there, open the top and see what color it is. If it smells and looks like Transmission fluid, then that means you have a busted radiatior. If you open the radiatior cap and look down into it and see the that the color of the fluid is a pepto bismal- looking color, then its deffinatley time for a radiator replacement and flushing of old fluid out of the system.
-3. Transmission is burning up gears and needs to be replaced. i dont know what jeep was thinking when they put a three speed transmission in a car of that size that idles high beacuse of the gears, when it should be a five speed that idles lower being thats a bigger size car.
-4. Check your fuel lines and your fuel filter.
-5. The sensor that sends a signal to the number one cylinder to fire may have gone bad and needs to be replaced.

Crank position sensors are a big problem in these vehicles. Scan the Jeeps computer and post any codes you come up with.

it most definately is the crank shaft sensor. same exact prob i had. it costs about 60 bucks and 3 minutes to replace yourself. one bolt holds it into the transmission bell housing and one connector wire. very simple fix. call off the wrecker. just have plenty of ratchet extensions available i had to go in from behind the transfer case to reach the bolt but it was still pretty simple to install.

Do you have an alarm on this? If you do, that is most likely the problem. There seems to be a problem with the alarms. You may want to have a new key made just in case. Sometimes the keys are magnetically charged and after time, it wears off.
