'14 Silverado Remote Start Issue

[14LTZ-1LZ]

Remote start will only work 3 consecutive times for 10 minutes at a time before you have to manually start your truck, then it's reset. Have you notice when you lock your truck with the FOB does the horn sounds, if not you have a door ajar or hood not shut. The horn sounding is your indication that's something is not closed properly. If your battery has a low charge a bunch of weird electrical things will occur. You should bring it to one of auto parts change store they usually check your battery for free. Have them load test it and if they are able to check for bad cells.

I have searched and searched. I cannot find the issue. I tested my battery and alternator and they are both good. I put a multimeter to the battery as it's being started and it only dropped down to 11.5V. Does anyone have any other ideas?

I'm still having issues as well, they seem intermittent. I'm going to clean grounds next and possibly run another to the frame given the one behind the engine is tough to get at.

I figured out the issue with my remote start. It was an O2 sensor code. My truck does not have a physical check engine light. It does not illuminate at all. I tested it my looking when my truck does the self-check upon startup.  The previous owner must have disconnected it somehow. I bought a tuner, ran the codes and there it was. If I clear the codes, it does not recognize the issue and works perfect. Four new O2 sensors later and we will see how it does.
