My 1992 F 350 Dually keeps flooding when I crank it up after a short period of time. I've just chged the spark plugs, and the air filters. But I still am having the same problems. Some help would be very much appreciated. THanks

 

Rent/acquire/buy a fuel pressure gauge and hook it up. Have a friend cycle the key on-off a few times, it should go up to about 39-40 PSI and hold there. If the pressure starts to drop once the fuel pump turns off, then you could have a leaking injector.

Another possibility is a bad engine coolant temperature sensor.

As always, check the codes before buying any parts.

 

Ok i'll check it out and get back to you

 

One more thing it could be is a bad air intake temp sensor.
