Engine Mechanical problem
1994 Ford F150 6 cyl Two Wheel Drive Manual

my truck will start up ok run and idle ok touch the gas and it hesitates for a split second. you kill it wait 5 seconds and it does not want to restart like it is flooded. let sit and later will restart.....i just changed the oil and it was HORRIBLY black and smelt of gas but did not have gas in it...FYI so i am assuming it is running way to rich..it also smells of raw gas after killing it

Probable causes of an engine running rich are as follows:

1.Fuel pressure not within specs.Can be cause by restricted fuel return line or defective fuel pressure regulator.
2.Defective Oxygen Sensors.
3.Leaking injectors.
4.Coolant temperature sensor out of calibration.
5.Restricted air intake system.
