cam sensop blowing problem

my 1995 7.3 blows cam sensors. i have already replaced the following part trying to fix this problem. i replaced the cam sensor wiring harness plug, the main computer,idm,all 4 valve cover plug on the main wiring harness,both valve cover gaskets,glow plugs,all 4 wireing harness plug under valve cover that go to the glow plus and injectors.i have a new ipr valve,but haven't put it on yet.the truck runs great untill it blows the cam sensor.when the cam sensor blows it acks like it is running out of fuel but it isn't running out of fuel.when the cam sensor blow i can put another one in and it fires right up and runs great untill it blows the cam sensor.i have put a snap on computer on it and all it says is cam sensor error. i was thinking of replacing the entire main engine wireing harness. i was thinking maybe that some of the wire on the wireing harness has a short in them which was causing the cam sensor to blow.what do you all think?i don't want to waste anymore money on parts that this truck doesn't need.all the part i have put on were good since the thruck still has the same problem.is there anything else that i haven't replaced that will cause the cam sensor to blow?any help will be much apperated!!! thanks in advance.

I heird on another forum that the gray cam sensops are junk. that the black cam sensors r the best one to buy .The guy gave me the part number for the correct black cam sensor to buy. This is is the part number he gave me,let me know what you guys think if thid could be what fixxes my truck. the # is K4TZ12KO73C. What do you all think? I am also tired of buying cam sensors from auto zone, advanced auto parts and car quist.I was thinking of buying one from theinternatinal dealer "aka" Maudlin Internation out of Palm Bay Florida. when i went to the local ford dealership to buy the cam sensor plug they sold me the wrong one for $75 and told me to file it down to make it fit.i went to Maudlin International for the right plug. they had to order it took two days to get it in ans it was only $16 ans some change. so do you think they would have the right cam sensor for my truck?

Do you have any scuff marks on the sensor end? I've read there could be a problem with something inside timing chain cover out of kilter,just a thought sense you have tried evrything else.Hopefully someone with more experience will chime in.

i still have the same problem with the truck blowing cam sensor.i just got done putting more parts on it and still the same problem.i just put a a ipr valve on it and a new fuel pump that goes on top of the motor.i also found a wire that had a bare spot on it. the wire plugged into the fuel filter housing.it went to a sensor on it.i am over putting parts on this truck and it not fixing the problem.the weird thing is that when the cam sensor started going out i changed fuel tanks and it ran good for a minute or 2 then went out started acting up again. when the sensor goes out,it acts like it is running out of fuel.i just don't know what the problem could be.i have so much money in new part now i could have took it to the dealership and payed them to fix it.howmany fuel pumps does this truck have on it.it has 2 tanks.
