I have had this problem a few times on my 2003 Grand Cherokee. After the guages go crazy then the thing will not start. First two times I replaced the battery and it fixed the problem for a short time. The real problem was corrosion on the battery cable(positive/red cable) I took some Coke and a wire brush and cleaned the cable, ends and battery terminal. This fixed the issue.

If the battery is good and connections are also good.you might check your belt's for slippage,or the belt tension pulley,if all, that is good it's possible your alternator is putting out enough voltage,back to supply the battery.

I have a 99 jeep grand cherokee 4.7, the alarm went crazy and the wont start. guages dont budge and horn keeps honking and lights flashing. sentry key light is on in guage cluster any help


Sounds like you need to perform a relearn on the anti theft system, it's not recognizing the key if this happens with the key inserted. Might want to look online for a reset procedure for Jeep. GM has you keeping the key in the ignition in the on position for 10 minutes.

Have a 2008 jeep grand cherokee laredo put key in ignition and dash board says damaged key and another service security key jeep wont start


This sounds like a bad chip in the key, try a spare key, if it starts with spare key then key is bad, if it doesnt start then you will need reprograming

2000 Jeep Grand cherokee Laredo wont start. Engine turn over . No noise from fuel pump with ignition on. Replaced fuel pump and filter.Turn ignition on- pump did not run.Jumped the fuel pump at the pump...


sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

Guages when crazy. Now won't even try to start.


You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)
