    2001 Sport Trac Intermittant Starting

    I have a 2001 Fort Sport Trac 170k 4.0 V6 2wd a couple weeks ago I drove home and a few minutes later went to start it and it just cranks. Checked the fuel cutoff switch all good, replaced the fuel pump relay no help It will start when it's cold fine but if u run it it wont start when hot once...
