3.0 cold weather starting (in Alaska)

[SteveinAlaska]

Hello to all after an extended absence. Surviving Covid & whatever else is out there. Anyway, finished out 2019 and went into 2020 expecting to spend some money on my workhorse, everyday driver. Covid hit & the truck sat for almost 4 months. Did not get out to drive it until warm weather (mid May 2020) Got into cold weather (October 2020) and it went belly up on me. Spring 2021 (again May) finally diagnosed and replaced ORIGINAL distributor cap,rotor and plug wires along with the damaged starter as a result of motor back firing,etc. As of today I have put the truck in a reputable local shop and they have replaced the mass airflow sensor along with oil changes & other misc. fixes. At this point I have been told that are going through a "wet cycling" process to reset the computer/black box/ ecm module. This I can understand as I retired myself from working as an auto tech about 1980 when those little black boxes came on the scene. QUESTION TO THE GROUP ...........Given that this is a 1992 model with 114,000 miles and almost 30 years old, could I anticipate replacing the ecm module or whatever black box is in this rig? I on more than one occasion let the battery run down because I left the interior light on (blame that one on old age) & in the course of use also disconnecting the battery (starter replacement). As I write this we are going from -40f to zero degree weather in the next couple of days. Appreciate any thoughts, suggestions on this.

ECM failure is fairly rare, they are not a wear item. If the truck runs OK when you get it back then the ECM is probably in fine shape and more than likely will far outlast the rest of the truck.
