I have a 1999 Chevy 3500 Van with a 350, ran find Sat. Set Sunday, Monday AM turned over find but would not start, had same problem about 3 mounth ago, replaced cam sensor in dist. And has run find until Monday.
Monday I checked the fuel pressure (65psi), replaced cam sensor, ignition module, and crank sensor, getting plenty of fire from the coil and at each plug wire, but it still will not start.
