I am wanting some ideas. I am having issues with a 2000 safari van it will start and run sometimes.When you drive it for the first time of the day it will run fine but shut it off and go to restart it and it wont start. now its not the charging system. it acts like fuel problems. changed fuel filter put, new air cleaner on it, new pcv valve new rotor. maybe fuel pump? when you turn the key you can here the fuel pump prime and once it starts it runs good. any ideas anybody?
