My ford sports trac overheated, we placed he radiator, but now water coming out of engine nd will ot start

Have you already confirmed that the coolant overflow tank has at least the minimum coolant in it?
Does the water level in the coolant overflow get higher when the engine is heated up than when it was first started?
At what speed does this happen? Idling only, or also when driving 35+ miles an hour.
A quick test - when the engine is warmed up, touch the radiator. If it is still cool, the problem is likely the thermostat - it probably isn't opening when the engine gets hot.

The car may have blown a head gasket, so that it boils all the water away. Do not drive it without water in it, it will destroy the engine.

Is it possible you only recently noticed this? All vehicles have a "lamp test" and or gauges test when the key is first switched on, Check your owners manual. If the engine isn't overheating you're chasing a non-problem and that's good because you can stop without spending another dime on the issue.

Make sure you don't have an OVERHEATING problem. Engine damage is sure to occur if it's running too hot. don-ohio

Did the engine overheat before the water pump was replaced? If so, you may have a warped cylinder head and/or blown head gasket.

Was the radiator full of rusty-colored liquid before you flushed it? If so, your radiator is probably restricted with rust deposits in the cooling tubes. Flushing WILL NOT get this stuff out. The radiator MUST be replaced if this is the case. Your heater core is probably not in real good shape either, so you should be expecting some heating problems this winter.

If the above is not the correct answer, then you should check to make sure the temperature gauge is not "LYING" to you. This could be caused by a defective gauge, a bad temperature sending unit, or faulty wiring.

The way to check this is with a scan tool that can read engine data and an infrared thermometer. While reading the coolant temperature data from the computer, check the cylinder head temperature with the infrared thermomometer. The readings you get should be within 5 degrees (F) of each other. If the computer data does not match the thermometer within the 5 degrees, then the sending unit for the computer should be replaced.

Then look at the gauge to see if the gauge reading is appropriate to the temperature readings that you took. Normal operating temperature is between 190 and 230 degrees. This should place the gauge at slightly to the right of center to about 5/8ths of the way to HOT. If the readings you took are OK and the gauge is reading higher than this, then you should try replacing the temperature sending unit for the gauge and see if that fixes the problem.

Please note that there are TWO temp sending units: One for the gauge and one for the computer.

Is it coming from your belt? Where is it coming from? You might have a pulley sticking.

Sound like the tube that connects your heater core to the water supply from radiator. On Fords these tube are metal and very oftern rust out and need to be replaced. This is located behind and to the right (passenger) side of the engine.
