#11 of 36 Re: Disable the factory alarm system on a 1997 Jeep Grand Cherokee by yourself? [leesville]
Apr 22, 2010 (12:14 pm)
I did this to a grand cherokee that the alarm would go off every time it was tried to be started, it took care of the alarm,however it still will only run about 30-45 seconds after starting, could this be part of the security shutting it down or another ,different problem? I am leaning toward a different prob. because if you keep spraying start fluid in it will continue to run. thanks in advance
#12 of 36 99 Grand Cherokee Won't Start/ please help!!!!

I have a 99 Grand cherokee that was working flawlessly until thes last weekend. My daughter was watching a movie inside while we were setting up for a camping trip. after about 20 minutes of getting in and out we decided to see if it would start. We did this about 2-3 times until we were finished. We went to start the vehicle the next morning and all it will do is turn over, no start though. There is a new icon in the dash now. once all the icons disapear the one that comes back on is the one of the key with a circle and line through it. I was told this is the anti-theft icon and that I was in a "hard theft mode" I have no idea how to fix it. I tried disconnecting the battery for 24 hours hoping to drain the system, I was told to unlock the vehicle manually on the rear and passenger door to reset, But there is only one manual door lock and that is on the driver door. It has no power to the fuel pump, but the fule pump works fine. I dropped the tank and checked as I thought the pump had gone bad. There is power to all fuses and relays. It just turns over and does nothing. I cannot believe that it is the key because it should at least start for 2 seconds then turn off. At least that is what it did a couple of months ago when I had a key made just to unlock the doors. I tried it in the ignition and it started then shut down after 2 seconds. I really need this car to work as it is my only means of transportation at this point and connot afford a dealer fix. Any info would be greatly appreciated.....Thanks.

try a different key
use only the key no other stuff on the key ring
make sure that you are using the key that you know is good still sounds as if anti theft unit is still coming on

The only other key I have is a spare I had made at Home Depot just to get me in the vehicle when we lock our keys inside. I know this will not start the vehicle as I have tried and it is not coded to the vehicle. But back in the day when I had the key made, I did try to start the vehicle and it would in fact start it then it would shut off after 2 seconds. The original key that I still have for the vehicle won't even start it for the 2 seconds. It will only turn over, nothing else. I will go home and try the "spare key" but I am petty sure it will do the same. Am I right in assuming the icon that comes on the dash with the picture of the key with the circle around it and a line through it is the anti-theft light. And if it is still on when the original key is in the ignition where does that leave me??

Also, While I was looking all over for a short somewhere I did notice there is a small hinged plastic covered bracket inside the driver door jamb that slides through a small box mounted inside the driver door. That small hinged bracket has all/most of the plastic broken off of the bracket leaving the exposed metal. What is this for. It does not have enough support for the door itself and I did not see any wires coming from the box in which it slides through. Any thoughts???

could be the door stop that has all the coating worn off its bout half way between the upper hinge and the wire protector
yes if the light with the key is on the car is in protect mode some will not start at all once code is set (sorry to say that i dont know how to turn it off )

my light comes on while driving, stays solid, not blinking. she still runs but has died on me a few times.... but always starts right back up. did you ever get it fixed?? it points to the SKIM (SECURITY KEY IMMOBILIZATION MODULE) as having a fault..?? but it only happens when the temperature is under 45 degrees. so i am thinking a bad connection somewhere....
