i have a 99 f150, i had a viper alarm system put into it. this morning my wife set the alarm off and since then i have not been able to start the truck. it has plenty of juice, but when i try to start it, i get nothing. i disconnected the alarm like the installer recommended and still nothing. he mentioned that it had a factory anti-theft device in it, has anyone heard of such a thing? Does anyone have any thoughts about this?
I don't know about the factory kill switch, but do you know about the fuel pump shut off switch? If you do quit reading if you don't look under your passenger side kick panel (that's where its at on my 98) and see if it got tripped. It it did just unplug it and plug it back in and it should pop back up. They may have run some wires down there when they were installing your alarm, and sometimes wires don't like each other and can do some wierd things to your truck!
