2010 sierrs,basic package truck.no keyless entry.
prostart remote,fortin set in programming.
goes through the motions,ign powers up,passlock lights and goes out,but wont crank.
if i start with key,shut off and hit remote,it will remote start immediately without issue.wait one minute and it wont crank engine.
i'm baffled..frustrating for something thats supposed to simplify things.
am i missing a programming setting? perhaps a wire needs connected?
tried faq's havent got anywhere.
couple hour job is now onto 5 hours.
