Were you having this problem before you worked on it? Double check your work, maybe you knocked a connector loose, somewhere? Use a spark tester, see if you have any spark at the spark plugs, engine cranking.
If you suspect the coolant temp sensor, use a digital multimeter, at the two wire connector, key on, should be around 5 volts.
