Went to start the truck this morning but wouldn't start. Checked for codes. i got P0743 and P1765. Looked them up in the DTR wiki, but what would you guess? They're not listed. Any idea what they mean?
I'm thinking i could have VP 44 problems or air in the fuel lines. I'm going to try cracking some fuel lines and try to start again. I might be able to have a friend drive me to the parts store to borrow a scanner later today.
Thanks for the help guys

 

P0743 = An open or shorted condition detected in the torque
converter part throttle unlock solenoid control circuit (3 or
4-speed auto. trans. only)

P1765 (M) Trans 12 Volt Supply Relay CTRL
Circuit
An open or shorted condition is detected in the
Transmission Relay control circuit. This relay supplies
power to the TCC

P1765 (M) Trans 12 Volt Supply Relay Ctrl
Circuit
Current state of solenoid output port is different than
expected (4-speed auto. trans. only).

this is what i found in the service manual....
Hope this helps
