i have a 2003 7.3 powerstroke and i put in a new IDM and it helped it to where it would atleast idle for about 10 to 20 seconds but thats it, the only code it is throwing is P0470, oil pressure is good and fuel pressure is good too, any ideas on why it wont run?

 

Thats a backpressure sensor code you can try cleaning the sensor.
