Thanks for choosing FixYa and welcome to the site. You can disable the alarm but you have to make sure it is the right wire and that you ground it. I would advise you to call the dealership and get the code to reset the alarm. Just make sure you have all your vehicle information with you when you make the call.

4wd flashing 2000 jimmy

Usually the flashing light means the 4wd system is disabled and can not be used.
In most cases you would need to get the body computer scanned for trouble codes.

2001gmc jimmy starts and stalls security light stays on

The security light has one job, it warns you that there is a "break" or "miscommunication" in your antitheft system. This is why the Jimmy keeps stalling. The antitheft system cuts the power to the injectors (It's thinking it is protecting itself from theft) and the vehicles stalls in 5 seconds or less after starting. They are also known to stall while driving. Followed by the security light. The SECURITY light will either flash or stay on solid. A solid light normally indicates a bad Theft Deterrent Module, this is the brain of the whole system. Go to this link, it has alot of info stuff that should help you out.

2000 jimmy. Security flashes. Think passlock disabled fuel. Can I fix it?

yes. 1st make sure u have the key with the black thick key grip. not the key with only metal on it, that one probably wont work, anyhow start by makin sure batt fully charged, if not put on charger while programming key. ok then to program all u do is close all doors an trunk put key in ignition turn it on all the way to run and leave it like that for approx 20 to 30min, after that then simply shut off key an try to start engine, ur security light shouldve stopped flashing an ur engine should start .... good luck hope this was helpful

Stalled out while driving and now will not start,, almost as if it is not getting any gas

try this turn your key to the on possition the dash lights will start to flash leave them flashing untill the stop flashing takes about 10 minutes. this is an ignition learning sequence and is a know failure for 98 thru 04 chevy and gmc trucks and suv's then see if it will start.
if you car has a security system factory or aftermarket disable it. i just went throiugh this problem with my wifes blazer. it turned over fine but didnt even try to start. the ignition sequence should allow you to start it. post your out come and we can go from there
