Alarm Problem on a 1997 Limited

Hello friends of JeepForum!!

This is my first thread here, and I hope I can be as helpfull to you as you to me.

My name is Bruno, I'm from Buenos Aires, Argentina, so excuse me for my bad English, anyway, I'll try to do my best.

Recently me and my father Pablo bougth a 1997 Grand Cherokee 5.2 V8 Limited, as it is an exportation model, it's a ZG Cherokee, not ZJ.

I bought it to an insurance company at half the price, because it was stolen and then recovered by them.

Because of this, the Cherokee didn't bring any key and any RKE Transmiter.

After changing the fuel pump because we get to know that it wasn't working at all and after replacing all the fuses, relays and the battery, we tried to start the car.

The Cherokee started, but it stopped a few seconds later. It does the same thing since then.

Investigating we heard that it was the alarm that came with the Jeep the one that was stopping the engine, and since then we cannot start our Cherokee.

We removed the liftgate's trim panel and tried to manualy lock/unlock the liftgate, as if we were using a key.

We assumed that this would disable the alarm, but it didn't.

How is the procedures to disarm the alarm with the key in the liftgate? Do you think that locking and unlocking from the inside of the Cherokee may work?

Anyway we've already taken out the liftgate's lock cylinder in order to make a key.

We've also removed both front door's trim panels, but we cannot find the violet/yellow wire. Do you know if that method can be used in my 1997 ZG Grand Cherokee? I'm talking about finding that wire and grounding it. In which door is located the wire?

Any ideas you can give us would be very thanked, and hopefully we can start this beautiful car, so we can enjoy it.

Thank you very much!!

Bruno & Pablo

I can show you photos of anywhere of the car, just ask for them!!

A Chrysler/Dodge/Jeep dealership should be able to help you. You will need the Vehicle Identification Number (VIN) along with proof of your identification and proof of ownership. The purpose of the security system is to make it very difficult to drive the vehicle even if someone (like a thief) was able to tow it away. To me it does not seem ethical or even legal for someone to post the kind of information you are asking for on the internet.
