valet 562t, 97 chevy truck won't start

i have a 97 chev p/u, problem --truck wont start with the key, only starts and shuts down with the remote, if i try to start with key i get nothing, just turns over. i remove the key, hit the button, --light s turn on a 10- 15 second delay--starter engages truk starts, i bought the truck with the system in it it was installed already but they did a horrrible job and not all features work can any one helpfabman

they probably hardwired a relay antitheft bypass the wrong way. do you have a small black and silver piece sticking out of the metal part of your key? if so, they wired it so that whatever bypass they used is on all of the time. so when you go to start with the key, the truck senses double the resistance and wont let you start

 when you remote start and then put the key in and turn it on and then step on the brake does the truck stay running? or does it stop?

no nothing on my key, ive had the truck for 2 years no problem, just started happening, thanksfabman

is there a guide, schematic that shows the wires (colors) from alarm system to the wires of my truck? looking at the install manual for the 562t it looks like not everything is hooked the way it should be, i talked to the previous owner, he told me that the factory system went bad and he wired this one into most of the wireing that it used, which probably is wrong . therefor i think it would be best to completely start over. im capable of doing it myself and im scared that if i took it to a shop, they would charge me an arm and a leg that i cant right now afford. i only need this truck to last me through the winterfabman

ok.....so if you put the key in and turn it on then press the button 2 times to stop the remote start, does the truck stay running on its own with just the key?? im asking you this because that truck doesnt have VATS or PASSLOCK, and so im thinking you have a bad ignition switch. the brake shutdown wire sounds like its not hooked up as well.

when i psh the butto n twice, the truck shuts down, even with the key on. where is the ignition switch located? doe you know?thank youfabman
