Cigar lighter, not the accy ports.

That usually either means that the OBDII port fuse is blown or the PCM isn't powering up.

That can happen if the PCM doesn't power up (as well as from other causes).

Did you check to see if F30 is HOT IN RUN or START?

 

Have you confirmed that voltage at the fuel pump is 12v . I do not know the threshold but i know it won't run with 8 volts. I had a bad fuel pump relay which on my '03 f350 was located on the circuit board in the main fuse panel ( in front of drivers left knee ).

If all fuses and other connections are good and you still get that error, it's likely your PCM took a dump. Mine had a damaged capacitor caused by the previous owner roughly installing a performance chip and it would stall/no-start intermittently. Immediately after a stall/no-start I plugged in my code reader and it wouldn't establish a link. Swapped in a refurbished PCM and so far it's been fine.

EDIT: Now that I think about it, if the code reader powered up that means the OBDII port has power.

 

All the fuses are good. Took it back to the mechanic as I don't have time to keep jacking with it after work. I will post what the problem is after he gets it fixed.

 

Got an update. My mechanic says the PCM is dead.

 

That sounds about right. Do they have a replacement on order? There are companies that can repair your old one, and there are other companies that sell remanufactured units.

 

yes a replacement is on order so hopefully that will get the truck going

 

Replaced the PCM, truck is alive again and running good.

 

Great! What did they charge, if you don't mind my asking?

 

He charged me $400 after diagnosing and installing a used pcm.

 

That sounds about reasonable.
