What would make a 1991 Toyota pickup 22r 4/4 not start unless it sit for a few mins after driving and turn it off

and old carb based engine
if engine has good compression, and spark is good and timed.
its a bad carb.
carbs:
1:float level good?
2; jets clean
3:all air emulsion tubes inside clear.?
4: choke set right.?

what motor is in it and does it?

Check your set screw, and make sure it's not too low. Adjust the screw to the point that where it idles at the proper speed. Also, maybe check your throttle cable for too much slack.

check fans and check thermostat remove it completely if you have to also check vacum lines for the idoling problem

Seems like the choke is not turning on. The 22r uses a carb if I'm not mistaken. pump it a couple of times then try pressing the pedal completely down before trying to start it. Then press the pedal half way down. the point is to set the choke when you press the pedal all the way down.

Replace the needle and seat in the carby , it's worn and flooding the engine at low speed.

could be the cold start injector or cold start injector sensor

Find the EGR valve and underneath the valve there are holes, with the engine running try to open the valve by using a scredriver, the engine should die. do it a few times to clean the valve.

is it a 22r or 22re?car or fuel injection?

I had a similar problem and it turned out to be the rubber fuel lines being old and cracked. The hoses would warm up and fuel would squirt out of the cracks. I had to replace three fuel line hoses and it has been running great ever since. Good luck.
