You are now. I've moved your thread to the 1999 - 2003 7.3L Powerstroke Diesel forum. You'll get a wealth of outstanding information from these folks.....they're great.

 

Ok guys I really appreciate it. Hello ford People, I have a 2003 f350 7.3, it's been giving me some problems it will run fine and unexpectedly shut off it might cranck back or it mighty crank the next day. It is real unreliable right now. I have a scan tool and sometimes it will link up and sometimes it won't but in always will link if the check engin light is off. I did get to pull some codes. Hear they are, hope fully someone can tell me if one of them will make my truck act this way. Input turdine speed sensor a circuit, shift solenoid c, system voltage, icp failure / cct test.*

 

One thing I left out when it won't start the wait to start light won't go out for a wile

 

Thanks John

Is the vehicle acting up right now? If it won't start right now maybe you could get us some live data while cranking and we can analyze that data.

 

Let me run out out and try it

 

Yea it will run right now

 

When it won't run my scan tool says waiting for vehicle to respond then it will say no response check plug, make sure ignition is on and stuff like that. When it will run it will always connect.

 

Well that's good but not good to help see what is going on.

 

Have you looked at the PCM relay? Or tried swapping it with the blower relay? There are also diodes that can fail.

 

No I don't have a owners Manuel so I dont have a map of fuses or relays
