2011 Chevy Suburban Wont Start

Asked by aflores8608 Jan 07, 2020 at 10:37 PM about the 2011 Chevrolet Suburban 1500 LT 4WD

Question type: Maintenance & Repair

My 2011 Chevy Suburban will not start. When I turn the key all the lights come
one and nothing. I replaced the battery, alternator, ignition switch and starter
twice. Hoping one of these were the issue. What could it possibly be?

You need to follow a troubleshooting procedure otherwise you'll be guessing and throwing money into it and still not correct the issue. Assuming you meant it does not crank. First try shifting from Park to neutral and back to Park, if still nothing, Check the battery cables for corrosion and make sure they're tight, don't forget the one by the starter. If cables are ok, check battery voltage,it should be minimum 12.4. check voltage signal at the starter solenoid as you try to start it, if voltage is present and still doesn't crank, replace starter. If no voltage present, trace back to fuse, relay, neutral switch or ignition switch
