How to reset default due to over cranking and not starting due to cold

you need to find overheat cause
and then see if there was damage from that.
the ECU does NOT need a reset
but if h3LL bent.
you can 3 ways, like all cars. modern.
1: push reset on the scan tool button.
2: pull the ecu memory fuse for 5min.
3; PULL BATTERY NEG LUG AND BRICKs the NAV AND RADIO.

Your call.

#2 elaborated
IG-COIL fuse 20
DOme fuse 37 both in junction box. same names
rests PCM and immoblizer if opted

Battery has no crank power,check battery connection.

Cold reset
A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike NVRAM inititialization, a cold reset does not reset the page count, the paper tray sizes, language, or formatter number.
Note If an HP Jetdirect card is installed, remove it before performing a cold reset. Otherwise, the procedure will also reset all the HP Jetdirect settings as well as the printer settings.
To perform a cold reset
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 5 seconds, but not longer than 15 seconds. During this process, the Attention LED will turn on.
4 Release the GO button.
Note If both the Attention and the Ready LEDs turn on before you release the GO button, you must start the procedure again with step 1.
5 The printer's LEDs will begin cycling. The cold-reset process will
run until completion, and the printer will return to the ready state.

If not work, tris this

NVRAM initialization

CAUTION Only perform the following procedure if absolutely necessary.
Performing an NVRAM initialization resets some parameters that cannot be restored later.
NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable. It also performs a system reset.

NVRAM initialization resets the following:

• all menu settings to factory default values

• factory settings such as formatter number, page counts, and factory paper settings
  

To perform NVRAM initialization
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 20 seconds. During this process, the GO button, Attention, and Ready LEDs will each turn on.
4 Release the GO button.
5 The printer LEDs will begin cycling. The NVRAM-unit process will run until the printer is in the ready state.

Slower cranking in cold weather is normal due to the oil being thicker and other tolerances being tighter. As long as the engine fires within 3-5 seconds I wouldn't worry about it. If it cranks REAL slow or is excessively slow to start, I'd tune it up (plugs, wires, distributor cap, etc.) and change the oil to the lowest viscosity recommended. Also, I'd have the battery tested and replaced if it shows marginal.

Hello,

There may be water mixed with your fuel. water + cold = frozen fuel. Get some HEET from a local gas station to remove water from your fuel during the cold months.


If your car is Diesel it maybe that the Glow Plugs are not working.


The majority of the time this is due to the "Cold Cranking Amps" in your battery. Most batteries are only good until it gets down to a certain temperature. After the temperature reaches or goes below the minimum temperature, the car isn't going to start. Generally speaking, the battery will tell you on it's sticker or label how many "Cold Cranking Amps" your battery has (aka CCA Rating), and what temperature is the minimum temperature the car will be able to start at. Most of the time, it's limited to 0*F.

Take care.

This could be a problem with the battery. The battery may need more cranking amps to start the vechicle in cold weather. This could be due to an old battery and may be time for a new one.

SPARK PLUGS FOULED OUT DUE TO LEAKING FUEL INJECTORS OR THE FUEL FILTER PARTIALLY CLOGGED.THAT WILL MAKE CAR HARD TO COLD START.

Malfunctioning fuel system, Fuel injector[s] leaking
Check fuel pump,fuel pressure regulator/fuel filter also

Make sure you have good clean connections from battery to starter and ground. If all okay, you may want to have a starter draw test performed. 

maybe the crank position sensor, long starts are usually due to the fact the computer doesn't know where the NO.1 cylinder is, so he fires at random and eventually he nails it, therefore the car starts.

The crank position sensor tells the computer where the NO.1 piston is at and he knows when to send the spark, but u should have a check engine light on in this case.
