Hey everyone, i have a 2013 non-pp SHO I got about a year ago next month. Recently i’ve been having electric issues (99% sure it’s just my battery going out, jumping the car has fixed it not starting every time and it runs fine once it’s going). After i started experiencing this, wether it’s related or some coincidence, i started hearing a new ticking noise i hadn’t heard before. I know the fuel pump makes a noise that sounds like this, but it sounds more like it’s coming from where the timing chain cover would be on the engine and it’s different than it’s been over the last year. I plan on replacing the battery when I can swing the cost of it, but is there any way for me to investigate the new ticking noise? Hooked it up to a scanner this weekend and i didn’t get any codes, everything passed the smell test, and if something was wrong it’d be something i’m not familiar with. my guess if anything was wrong, it’d be either the timing chain and water pump (76k miles, haven’t been replaced yet), but i don’t know how to check if they’re good or going out, and i don’t have the tools to rip out the engine myself and to check. Is there anything else i should be considering? am i just reading into this too much? or is it worth the poking and prodding?

I would work on getting the battery replaced and the BMS reset. Weak batteries will cause lots of gremlins.
Already in the plans for the most part but the BMS is new to me, could you tell me what that is or point me in the direction of where i could learn more about it/resetting it?
Battery Monitoring System - There is a sensor on the negative battery cable that monitors current use. The body control module keeps track of battery age (in days) and state of charge (in percent). A scan tool is used to reset the BMS so that the battery charges properly. After installing a new battery the BMS will reset automatically if the car sits for 8 or more hours undisturbed. However, only a scan will reset the day count. Forscan and Forscan Lite can reset the BMS.
You can also set up gauges in Forscan Lite.

It should also be reset if you charge from the battery terminals. Technically, the "proper" way to charge the car is with the positive terminal on the battery and a remote ground location. The 8-hour reset also requires that the vehicle is fully locked and the ignition switch off. Some people have had issues with going to close to the car with the key on them since the system can "awaken" to look for keyless entry.
I disagree with this. The BMS should only be reset if a new battery is installed. If the battery is charged improperly, the BMS will eventually adjust the state of charge. Agree the proper way to charge is through positive cable and body ground.
Additionally, hiding out of sight under the red cover, the positive battery terminal grows corrosion. If you determine that it should be replaced, you have two options. Replace the whole terminal, fuse and cover assembly or replace just the positive clamp.

Okay! I appreciate both yalls help @Texas Marauder @Ta2dResqr, I checked the terminals and they look fine, and charging the battery has helped my issue with it not starting after sitting a few hours, however, I am gonna need to steal a better scanner that can reset the BMS since the one I was stealing from my little brother cant do that.
The rough idle and slight ticking haven't gone away though, and now I'm circling back to my timing chain and water pump again because this is different than how the car has run for the last year I've had it. Is there any way for me to check the life/health on those parts without physically getting to them and ripping the timing chain cover off? My neighbor has a fancy Snap-on scanner so im gonna bother him sometime later today to try and steal it and reset the BMS sensor and to see if anything else is out of place. Also considering new spark plugs to start throwing ish at the wall and seeing what fixes it. ANY ADVICE AT ALL WOULD BE GREATLY APPRECIATED!

If you have to keep jumping it to start it, change the battery and move on. My 2015 is on it's 3rd battery and I have never reset anything. I can assure you that the hundreds of thousands of Taurus owners needing to change their batteries haven't reset the BMS and don't know what it is to begin with. BMS keeps track of battery age? So does the sticker on the side of the battery. Also clearly not recommended by Ford or those same hundreds of thousands of people would be buying OBD II dongles, hooking up their laptops with FORSCAN to the car and performing this pointless manuever. That would mean anyone without that capability would have to have their car towed to the dealer for a battery change. Battery dies, change it.

It does not stop the car from working. It does not mean you have to get it towed in. There is a built-in reset method that when the car is left alone for 8 hrs, locked, and uninterrupted, it will reset. It does not merely track the age. It tracks use vs. charge. The BMS will disable and reduce power to items. It learns the health of your battery and its charge/discharge characteristics. When you are having electrical issues and you have charged, jumped, or replaced the battery, resetting the BMS can ensure that everything is in sync.
There are also plenty of people out there who have not changed spark plugs, changed PTU fluid, changed cabin filters, reset oil life monitors, reset TPMS, etc. Just because you don't have to, it does not mean it cannot help. And it IS clearly recommended by Ford. It is stated in the manual and in service procedures. It is far from a pointless maneuver on a vehicle that already is known to eat batteries.

Change the battery and move on with the million other Ford owners. Pointless.
I like this and gonna steal it if you dont mind...
People come to these forums to be educated by the collective that have gathered experience with working with this particular vehicle. I will agree with @Ta2dResqr not everything is pointless. Did you also know you can disable the BMS using Forscan? You can turn off this system, it will then put more strain on the alternator, to keep the battery charged all the time. The BMS is intricate, and yes throwing a new battery in doesn't reset it, the BMS does exist and for a reason. Following the proper method will keep people from replacing their battery prematurely. I destroyed a battery by charging it directly on the terminals. In less than a year without driving the car. The BMS was all messed up. My thought is - dont like the advice provided here - then take the car to a dealership - which is what Ford wants you to do.
When a majority of the voices here agree on the talking points, its because we have collectively learned the wrong way to do things. My advice, you can disagree, state that - and move to another thread.
Millions of Ford owners have to replace their vehicle's battery more frequently because they don't have the BMS reset. I went through that with three before I learned about the reset. I've been going solid on the latest one for quite a while now after learning to reset the BMS. Fingers crossed
You can use a scan tool to compare desired cam timing vs actual cam timing. Should be close to zero difference. 5 or more indicates chain stretch.
Remove the accessory drive belt and see if the noise goes away. If so, check the tensioner pulley, alternator and A/C pulley for roughness, looseness etc.

The battery in these cars are way more important than I believed, and I should have listened to all the good advice on here to that end. See https://shoforum.com/threads/replacing-battery.141086/post-1595726

I clean the battery terminals on my 2019 every 6 months.
