Need some help

I have a friend that has an '02 7.3 that will crank but not fire. I've already advised about swapping his CPS, but I loaned him my SCT to read any DTC's and he has no power there. Any suggestions?

Check the lighter fuse that powers the OBDII port.

If you mean no power to the obd port, I think that is on the same circuit as the cig lighter. Can't remember the fuse #.
Beat me to it.

Tell him to check the fuse that goes to the fuel heater. It is also the fuse that goes to the IDM. If it is blown, unplug the fuel heater (only electrical connection of the fuel bowl). Replace the fuse and carry on.
