My roommate has a 2002 F-150 with a 5.4 210,000 miles. The truck turned over last night but wouldn't start. We (reluctantly) sprayed a little starting fluid in the intake a couple of times and it fired up and made it home. As soon as we got home he tried starting again, it fired and died after about a second, and wouldn't start again last night or this morning. We're going to start at fuel filter and then go to fuel pump but was wondering if anyone had a similar issue and what they did to fix it. Thanks.
