I have a 2002 f350 with a 1999 7.3 in it.
While driving I lost all guages and the truck died.
I'm new to diesels and I'm not really sure where to start
My radio, lights etc. work I have no gauges and no power to the fuel pump. Any ideas? Thank you.

 

check fuses first, sounds like a short on ecm circuits, see if one is blown

 

I don't have a owners manual. All the fuses are good. But I'm not getting power to 22-33 or 42-48.

 

does the WTS light come on?

 

No I have nothing.

 

i think it's fuse #30. check it.

 

30 is good. Not lighting up though.

 

some those fuses wont have power unless you have headlights on or other accessories, id swap out the pcm relay with a another one then see what you have, then swap idm relay and see what happens, bottom two relays in first row next to fuse 14 and 18. does truck have a chip installed?

 

I'll give that a try here in a bit. And no chip. It's stock.

 

I still have nothing.
