DodgeForum.com - 95 5.9 won't start

I have a 95 long bed 4x4, standard cab dodge. Driving home truck started to sputter and miss, fuel read full. came home, let it sit for an hour went out to start; cranks but won't start, changed plugs (looked good), wires, cap, rotor, camshaft sensor, still no start; replaced crank position sensor,coil,and EGR transducer valve(looked like it got hot slightly melted), started ,it ran for a drive around the block, shut it off and then it wouldn't start again, cranks but no start. Fuel pressure was low 20psi, so took it to friends shop (needed help) and changed fuel pump (40 -45 psi), truck started, ran for a short test drive came back let it sit for a few, tried starting, cranks but no start, checked ignition, getting voltage to spark plug but won't start. anybody have any ideas why its not startting
