Default Re: 1996 F250 5.8L Starting Problems

Another thing that can cause your truck to run rich is a bad mass air flow sensor (changes Baro reading to PCM), i would get a fuel pressure gauge and test pressure - maybe a fuel line is kinked and the pump is deadheaded. Is your air filter/intake tract clogged?
