Changed out timing belt & water pump lined up all marks put back together. Truck started right up with no issues and was running smooth. I topped off transmission fluid while truck was running and then shut it down for the night. Got up to go to work following morning and truck would not start, cranks but doesn't start. There is a smell of fuel and there was some fuel in oil. I changed oil, spark plug wires, air filter and I have a new starter and battery. Any Ideas as to what might be causing this?

Probable causes of an engine running rich are as follows:

1. Excessive fuel pressure can be cause by restricted fuel return line
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.
