I'm hoping that I can be directed in the right direction to resolve an issue with my truck. Ibhave a 2010 chevy avalanche ltz and lately I havent been able to get it started when turning over the ignition. My remote alarm doesnt even work and get no response from truck. I have power to the panel, but when I try starting the engine, I get nothing.... Please advise.

The issue is intermittent. Sometimes after sitting for a while with battery disconnected it woukd start working. But now, this method doesnt work.

 

Check your battery cables for good solid connection and corrosion at both ends. Check the wires going to the starter also.

 

Battery is 6 months old and connections are good. No corrosion to terminals and cables to battery and starter. My truck will not even respond to the remote car alarm transmitter. When I have the ignition switch in the acc position, I have power to the panel. My ac turns on as well, but when I try to start the engine, nothing happens like its not getting any power to the start circuit.

 

Sometimes When truck engine is on, all my gauges on the intrument cluster panel zeroes out. My radio powers off as well. It doesnt affect driving but I'm not able to use my signal lights or able to roll my windows down. And my brake lighta do not work when this happens. If I turn off the truck and try restarting it, it doesn't start. I thought it maybe the anti theft system is going faulty and preventing it from starting. The problem is intermittent but getting worse. Ill have to wait it out and try to see if I can start the car. Can someone help?

 

 

My guess is body control module as everything you post that is an issue is controlled by it. If it were a fuse, that would be a one time deal.
