Howdy,
I have an 86 4runner 22re

Issue: Engine is cranking but not starting

It has started every time first try all winter and showed no signs of running rough. Outside temps warmed up to 38f then dropped down to below freezing. Next morning around 7am I couldn't start my truck... cranked and cranked pulled the spark plugs to check for spark and they sparked when cranked and looked fine. After putting the plugs back in at about 10:30 and truck fired up first try(it warmed up a bit, to near or slightly above 32) drove around and turned the truck off and on multiple times without an issue.

Went to work and came back out with the temps down to about 5f and the truck wont start... it's not warming up anytime soon and temp is now -3f.

Also I only had 1/8 tank of gas when it first would not start and then filled up when it did start. When it didn't start the second time I put in a bottle of yellow Heet.

Thoughts?

Replace the cold start injector time switch, near the thermostat housing.

Towed it to a heated garage and let it sit over night... fired right up the next day. I let it sit outside the next day and the temp dropped below -20 f and it fired right up the next morning.
