Ford Repair: 93 f150 302 no hot start, coolant temperature sensor, o2 sensor

Question
My 03 f150,302 engine has 224K miles on it and starts fine when cold runs fine at all speeds, but will not start when engine is at normal oper temp, although it seems to be cranking at hi enough revs. I did comp scan and replaced egr sensor and o2 sensor but did not correct. now the only error codes i get are 636 and 116.

Answer
Start by replacing the ECT which should be located on the heater hose rail.The other code is horse of another color.It has something to do with the transmission temperature being out of range.Replace the coolant temperature sensor and then go from there.Good luck.
