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.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
