When you took out the sparkplugs on your 1995 legacy 22 non turbo they were wet with gas and it would not start unless they were dry could it be the pressure regulator and where is it located thanks?
the traditional reason your spark plugs are wet (engine flooded) is your coolant temperature sensor. if it faults and says the engine is cold, the electronic control module (ecm) thinks the engine needs excess gas to start and it will flood the engine. next time it won't start, unplug all four fuel injectors. get back in and start the car (it will run for 10-20 seconds, then die). get back out and plug in the injectors. it should start right up. it this works, replace your coolant temperature sensor. your fuel economy will improve, too.
