3 years of flooding problems

FORD F-150

I have a 92 Ford f-150, 302 with 190,000 km.
For the past 3 winters I have been having problems with flooding. After several tune-ups, oil changes, 3 o2 sensors, new fpr, and 3 separate mechanics looking at it I don't know what to do next.
Also got a thorough injector cleaning done.
What do I try next? Do I change the ect, map sensor?
Please help.

Three things, Coolant temp sensor, which kinda acts like the choke on fuel injection, The check the fuel pressure regulator again! Third but rare. Stuck injectors. One more question. Does your truck have 2 small coolant lines atached to the TB?

Thanks for the quick reply Merlin.
I got the fpr changed in Dec.
Truck ran fine for 2 months. Thought everything was fine until about 6 weeks ago. Truck flooded but got it started. Mech. Told me to drive it like a teenager. He said the plugs were fouling and needed to be driven hard.
The ckech engine light did come on in mid January when temp was -40. Mech said that if it was running fine disregard the error codes. At that time codes were ect out of range.
Not sure about the coolant lines. This problem all started after I got a new rad, water pump, and timing chain.
I do have a small exhaust leak in the return.
