i have a 95 powerstroke 7.3 that dsnt run. i bought it from a friend that told me that he was driving it down the road and it slowly and slowly started dying. finaly it died completely and had it towed. i bought it and did a common fuel pressure test. well i had no fuel pressure so i changed the fuel pump and the cam sensor but still dsnt run. i crank and crank and get a sputter hear and there but no continues run... i had a friend with a computer check all the injectors and i have tested the glow plugs through the valve covers but not completely out of the truck.i wait 4 the glow plugs to kick on and off and still nothing but i get plenty of white smoke,kinda lost now any ideas?
