91 Es250 Starting Problem

Recommended Posts

When starting up a cold engine, it doesn't start right up especially in colder weather. Usually starts on 3rd or 4th try when turning the key for a couple seconds each try (wont start on 1 continuous cranking, must do a few short trys). Replaced the cold start valve and made no difference. Haven't replaced the fuel filter in years. When hot such as in summer, it starts 1st try. Any ideas on what might cause this?

bad plugswires can cause it, clogged fuel filter, faulty fuel pressure regulator, or fuel pump.
