Your post is kind of hard to decipher. I would start by checking the basics like all the underhood fuses (especially #9 and #22) and fuse #16 under the dash. Check the main oil level. If #22 is blown, unplug the fuel heater (probably shorted) on the driver's side of the fuel bowl about halfway down, replace the fuse and see if it starts. Cheers!

no blown fuses .... truck started next a.m. took it to a local guy that has had 7.3's he has been driving short trips round town for two days and it won't act up for him

when was the cam sensor last changed? I consider changing the cam sensor a 100k tuneup item on 7.3s...

also some OBDII readers are confused by PSDs.

psd???? changed cam sensor same day still would not start went out next mornin fired right up

PSD-PowerStroke Diesel. They are OBD2, but need some kind of add on for a scanner to work. It's my understanding that none of the cheap ones will and Auto Ingenuity is the only one that can read. I'd guess that a Snap On scanner would, but might still need som additional software.
