Remote Start not working

[Trytti]

My remote start on my 08 Silverado is not working. It worked when I purchased the truck a few months ago. Now when I try it it sounds like the remote motor is trying to run but the truck doesn't turn over. This is the first remote start vehicle so not sure exactly how it works. According to the manual it says hit the lock button until it flashes once then hit the start button ans hold 2-4 seconds and the lights should flash twice and then it should start the vehicle. The lights only flash once and the remote motor runs but it does not start. Any ideas? Not sure if I maybe messed up a setting or what?

Thanks

Is the check engine light on? If so the remote start will not work. I had a CEL and my remote start on a 2007 chev silverado did the same as yours. Fixed the issue and works again.

Go into the Driver Information settings and make sure remote start is turned on. Also, remote start will not work if you leave the key in the ignition.

Yep the cel light is on. Thanks for the info!
