No, not unless there was fuel in that vacuum hose, which you checked for?
Cold gasoline engines need to be Choked
Computer does this based on ECT(engine coolant temp) sensor, not the same as the Temp Sender for dash board temp gauge
With key on computer checks the coolant temp via ECT sensor
Under 140degF = some choke is used, the colder the temp the more choke is needed
"Choke" on gasoline engines means Richer fuel mix and higher idle, the colder it is the Richer the mix and the higher the idle
As engine(ECT) warms up the idle goes down and mix gets leaner
After a few minutes the computer switches to Closed Loop and uses O2 sensor to adjust air/fuel mix
(O2 sensors only last 12 years or 100k miles, cause richer running after that, they are the ONLY sensors that wear out)
If would be good to use an OBD2 reader to see what the computer sees from the ECT sensor at cold start and with a re-start warm
Bluetooth ELM327 reader is $15 and TorquePro APP is $5
Way cheaper than replacing sensors on speculation
Pull a couple of spark plugs on passenger side and see if their tips show darker color of Rich running
You can do the "Clear Flooded Engine" test to see if injectors are leaking
All Fuel injection computers have this mode: "Clear Flooded Engine"
Key on
Press gas pedal down to the floor all the way and hold it down
(when computer is on and sees 0 RPMs and WOT, wide open throttle, it will shut off fuel injectors, so driver can Clear a Flooded Engine, spark is still on)
Try to start
It should not start or fire, no fuel
If no start then injectors are not leaking, nor is the Pulse Damper
If it starts then could be fuel leaking in, but...................
Need to test if you have WOT at the throttle sensor
Use a stick against the seat to hold gas pedal down all the way
Go to the engine and see if you can manually open the throttle a bit more
If not then yes, fuel is leaking in
If you can open the throttle a bit more then Google: Ranger throttle cable mod
Very easy fix for stretched cable, to restore Full throttle, WOT
