My 1994 Jeep Grand Cherokee Laredo wont start, everytime I try to start it, it makes this loud noise like a buzzing sound, and then the security light starts flashing and the brights light starts flashing on the dash board.. The battery is brand new.. I don't know what the problem is..

Disabling horn beep for lock unlock and remote start follow this link for an in depth explanation but i think it is due to the alarm/remote start if fitted neediing to be re-synced hope this helps - what a nightmare

did you adjust the idler pully, to tighten up the belt?

Hi Andrew:
The 1994 Jeep Grand Cherokee Laredo Anti-Theft System is equipped with Vehicle Theft Security System (VTSS). VTSS system monitors vehicle doors, hood, liftgate and ignition. If an attempt is made to enter or operate vehicle without proper disarming of system, vehicle horn will sound, headlights, taillights and parking lights will flash, and engine will be prevented from running. I have an '93 GC 5.2L V8...

Herein you will find interconnection between electronics parts of the system such as body control module, auto headlamp light sensor.

I had the same problem on my 02 Grand Cherokee the truck was still under warranty and the dealer replaced all the rockers and problem was solved.

Contact the dealership and purchase the rear differential additive, this product assists the limited slip diff in opperating correctly. once purchased simply ad to the rear differential. it only takes about 250ml

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

check fuses under dash @ under hood the ones in black box

You can check fluid level by removing the rubber plug in the cover. Fluid is full when on level ground, it is just at the edge of the hole (or very close) if you are already getting noises out of there, you can remove the cover and inspect gears for wear or breakage. If you find a large amount of metal debris in the lube it tells you something bad is going on back there. Although rebuildable, it's not a home job...requires exact settings in order to operate properly. You can find good units far cheaper than even a gearset costs in any scrapyard. to match ratio, count the teeth on the ring gear and the pinion gear. the replacement MUST have the exact same number. Before swapping diffs, check all back there to make sure noise is not from somewhere else.

I have a 1994 jeep laredo. When I make a u turn there's a loud sound while making the turn and the car starts skipping until I turn the wheel straight. What causes that?
