Having problems with your 2002 Cadillac Escalade Ext ?
My 2003 cadillac escalade ext stalled yesterday & wont start. If it does start up it just runs for a second & shuts off. It has power & is deffinately not the battery. It turns over & seems like it wants to run but may not be getting fuel. My truck has 140,000 miles
This sounds to me like the antitheft security system. If the computer doesn't read the transponder frequency coming from the key, it goes into anti theft and shuts down the starter and/or the injectors. If it starts for 1 to 5 seconds and then shuts down, its probably this. Read up about this on this link, it gives you symptoms and causes, plus a "do it yourself" solution if you decide that this is the problem. I've been dealing in GM vats-passlock-passkey securities for quite a while now. From your description, I'd guess this is the issue. http://vatspasslockpasskeysecurityhelp.yolasite.com/
