Nissan pickup ka24de petrol version. It cranks good but does not start in very cold weather, backfires from throttle body. Change all four sparkplugs. Spark at plug and injector pulse was present. Ultimately I pulled from a truck at 30 speed for 3 minutes. Then it starts. It has been almost 7 days since pickup started without any issue. I don't know why there was backfire from throttle.

This sounds like low fuel pressure which will cause the problem you have described. To be sure let's remove one spark plug to see its condition if it is black in color. Let us know what happens and please upload pictures or videos of the problem.
