I own a 1996 Mercury Sable LS and ever since I purchased it from the previous owner I've noticed that it is hard to start after sitting for than 30 minutes. This is especially true in the morning when it will often crank for over 5 seconds before starting. If I turn the key on-off on-off on-off and prime the fuel pump then the car will start easier. This leads me to believe that there is a problem with the fuel pressure regulator. Another thing I've noticed is that I am only getting 16 miles per gallon with a mix of city and highway driving, when I should be getting closer to 23-24 mpg. I've heard a common symptom of a bad FPR is low miles per gallon. Is there a way to test this part without a fuel pressure gauge to see if it's malfunctioning? Could it possibly be the fuel filter or something with the fuel pump, or possibly a different part altogether? Any help would be greatly appreciated.
if switch is put off and on to start easier, sounds like fuel pump, keep in mind engine runs on water temperature, so if the weather is really cold and only driven short distance, fuel milage won't be good
