2006 RR Full size 4.4 206k. I took my truck for a drive yesterday (about 10-12 miles) then parked it in the driveway. About 2 hours later, I went to pull it into the garage and it won't start. It cranks fine, there is plenty of gas, no symptoms of anything before parking it. I checked all of the fuses, swapped out the fuel pump relay, tried starter fluid, disconnected the battery overnight and it still won't start.... I'm at a loss.
