I have a 95 5.0 and it randomly has trouble starting....I can hear the fuel pump and everything and it turns over but wont start and tonight i pulled a plug out to see if it had spark and it started right up withthe plug out. Put it back in started it went down the road and it died. Pulled that plug again and it started right back and then didnt have a problem after putting it back in again. Any insight would help
