I could not get the truck to fire up yesterday. It was parked for a few days, out on the street, and I just wanted to move it to the driveway.
I changed the fuel filter and it still did not want to start. Once it did, it installed and idled really rough for a long time. But once I finally got it back in the driveway, it seems to be starting fine.
I broke open the fuel filter to see how dirty it really was, and it did not seem to be too clogged. The only other thought I had is that the truck was parked on a hill for several days. And it sits pretty level in the driveway. I don't know if the incline affected the fuel flow or not.
