Hi 95 S...... I am actually picking up a fuel pressure gauge tonight. Will start truck and test pressure. The truck has 100000 miles...so would not be surprised if the pump is weak. As for spark, not sure.. it has only quit when I'm out on the road without tools. Seems to restart after 10 min or so, and gets me back home. I am also alone, so tough to test for spark and turn truck over at the same time. Might have to round up a helper.....
