dei 562t quit

You would have to check a few things in this case. first look on the drivers side under hood firewall.look for a PURPLE / white coming out to from inside sometimes you will have a few wires sometimes.if there is gray  that would be hood pin. it will be raped with black tape. trace this wire back to where it is going. sometimes you will find that it is disconnected from the car side white wire. look for signs of wire taps by ecm. soldering would be that best way for me. second is this can have a bypass mod by dei a little black box that would be under the drivers side dash. this would say 555l or 555lw this mod box can get glitched and stop working. this has happened when disconnecting the battery for service. the best thing to do is drop the dash and look for this black box. unplug it. then plug it back in.turn key on and start car. this will reprogram this bypass box. now try to remote start now. the last thing is this may not have the purple wire hooked up you can be in tackless mod you can lose program. this remote starter would have to be reprogrammed as that day it was new. please check your program book. hope this helps
