01 truck idles ok but when the pedel is push it goes up about 100 rpm and idles very rough and won't go above 1000 rpms, voltage is around 14V and have 16psi at the injector pump, thru code 1693 and the engine light is on put charger on and truck ran at a little higher rpm but still running rough, modes are listed below.

 

I'd try to read and clear the code and see if it is better. I had an Edge EZ that would cause this problem intermittently and set a code (1693 if memmory serves correctly , No communication between ECM and VP44). I cleared the code and unplugged the Edge data port connector and all was well. Ultimately, after changing the VP44 before I discovered the real problem, Edge fixed the EZ for nothing.

 

1693 is a companion code there is another one there

 

Yes it is showing 1594 and 0122 after it stalled and now won't start at all, and i noticed that all these code are to do with electrical. It al started while driving slowed down to let truck in front of me turn and as soon asI touched the pedal engine light came on and would only idle, thought fuel geled up and put some stuff in it and had to tow it then put it in warm shed went back to try and start it, would still only idle so while checking somethings out it all of a sudden started running as if it had 2 cylinders and then quit and now won't start w/ codes above.
