Toyota Repair: 4 Runner wont start when cold, coolant temp, cold start


Question
I've got a 89 4 Runner 22R with a big cold start problem, got to crank more then 10 times before it start and this only append at freezing temperature.I'm looking also for the resistance of the cold start injector and the coolant temp. sensor or any other informations.I already change the fuel filter and tuned up.

                    Thank you,

Answer
The cold start injector should have a resistance of 2-4 ohms. Also check the cold start time switch which controls the cold start injector, it's resistance should be 30-50 ohms below 50 degrees F, 70-90 ohms above 77 degrees.
Remove the cold start injector from the intake chamber and leave the fuel line and electrical connector hooked up and crank the engine over, there should be fuel spray from the injector while cranking.
