hey guys i got a problem. i just bought a 95 f-350 powerstroke with a 5spd 4x4. it ran fine on the way home, the next morning the batteries had drained down somehow and wouldnt start so i put some different batteries in charged them up and now it just cranks and cranks and cranks it acts like its not gettin any fuel at all now, at first it would puff alot of white smoke but now its nothing no smoke absolutly nothing i put a new cam sensor in from an auto parts store but it still wouldnt start did the same thing, is it possible i got a bad sensor the tach wouldnt even budge when i was cranking it before and now it still doesnt with the new sensor i checked and rechecked the conections but they where fine so im completely stumped, and i checked the fuel filter it appears fine and the fuel bowl was full of fuel. so whats the next thing to do? get a different sensor? i also checked the oil its about half a quart low so that wouldnt afect the hpop? thanks alot in advance, ben.
