My 93 Legacy SS has a starting problem which doesnt happent every time I start the car, but happens frequently. I just installed new NGK plugs and wires, fuel filter, air filter, pcv valve etc. Latest incident, car sat all day, then Thurs. night, it started perfectly. I drove about 3 miles to my parents house, and shut it off and was off for about 2 hours, then when I went to come home, It wouldnt start. First two turns no start, then on third turn it barely started and was sputtering, gave it some gas and all is normal. I must mention that the car ran great before and after the tune-up, its just this occassional starting problem. Can somone shed some light on what it could be. I have heard that it could be a fuel pump issue or coolant sensor, what gives. Help me out please.

new coil? if not, get one and see.

Coolant Temp Sensor first - cheap and easy to replace. Just for kicks, make sure all your vacuum tubes are tight and connected.

Did you unplug the fuel pump connectors to relieve fuel pressure when you changed the fuel filter?
