Question edited for clarity and correct spelling of model Lorado, to Laredo (it is a place in Texas). Question moved to model category. That information isn't available. You would be better parting it out for spares. The fires will have caused damage that is not cost effective to fix. https://www.google.com/search?q=1994+jeep+cherokee+fuse+box+wiring&sca_esv=574692167&rlz=1C1QJDB_enCA643CA644&tbm=isch&sxsrf=AM9HkKkcv4FGZAvlTY_mXKxhQKcFB928hA:1697688361300&source=lnms&sa=X&ved=2ahUKEwjXlNv9nYGCAxVYFFkFHXomCGsQ_AUoAXoECAEQAw&biw=1920&bih=931&dpr=1 Or give the job to a trained auto-electrician. https://www.google.com/search?q=auto+electrician+near+me //

Question edited for clarity.Question moved to model category.It could be many things and it is no good guessing. An auto electrician can connect a professional grade scan tool computer and record what happens at the moment it stalls. It is more cost effective that guessing and swapping out parts. It may just be a cracked wire or a bad connector.https://www.google.com/search?q=auto+electrician+near+mehttps://www.google.com/search?q=1999+Jeep+Grand+Cherokee+engine+stalls+while+driving..

Could be a dirty intake manifold and IAC valve. Spray some intake cleaner into the throttle body with the engine running to clean the system.

If computer sees no crank sensor signal it shuts down pulses to the injectors. But, you bring something new into the mix. Make sure fender grounding is good so the relay can operate properly and make sure power going to it is not restricted by a loose or dirty contact on the power side.

It appears that mine is located on drivers side fender to the right front of the booster

Fuel pump failure. Have someone open your gas cap an listen closely while you try to start the car. Your listening for a buzzing noises, if no noise pump has failed, very weak noise not enough pumping pressure to start the car. All 'n All "FUEL PUMP FAILURE"

Jeep has always had a problem down the line with the shifter linkage usuallly under the shifter, you have to take apart the console or column and locate whats broken inside there. I've had this issue myself with Cherokees too .

Watch this video. It is on a 2000 but may be close to the same as a 1999. https://www.youtube.com/watch?v=lBwpusnz8cE

In the fuel evap system you may have a defective leak detection pump.

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U can also get free manuals

The computer might have to be reset.Check you manual to see if you can reset it or try disconnecting the battery.

If the alarm goes off, it its because it was armed in the first place. You mist disarm it before entering the vehicle. To disarm it push the remote control unlock button or open eithe front door or liftgate using the key in the keylock.

is yiur batery in your key ok?

Look for a toasted relay. But look very well

Hi.

If fuel pressure is low and you have already replaced the fuel pump, then the problem is usually the fuel pressure regulator. The pressure regulator is in same assembly with fuel filter. The assembly is located to the fuel tank, bolted to the truck's frame. The pressure is tested connecting a gauge like this : Set Sealey VSE952 to the port on the fuel rail. The pressure on Grand Cherokee must be around 49 psi plus or minus 5 psi. If engine runs but pressure is below 44.2 psi , check for a blockage in fuel supply line between fuel rail and fuel pump module (e.g.kinked line). If the line is not blocked, replace fuel pressure regulator and filter. Test pressure with and without fuel cap on.

Another test to be done is reading pressure, then shutting the engine off with the gauge connected. If pressure goes down too quick, then the regulator is defective. After 5 minutes the pressure should not go below 24 psi. If it does replace the regulator.

If regulator is OK check for leaks at the injectors that can cause fuel pressure drops.To check for injectors leakage clamp off the rubber hose of the pressure gauge tool between fuel rail and the port. If pressure staysr above 24 psi and before was dropping, then a fuel injector or the fuel rail is leaking.

Below a diagram representing the fuel rail and test port. The engines from same years like your six cylinder have the port and rail in the same position.

is it all wheel drive? It's probably your front drive shaft. Very common.

check the heater core
