Only 2 of his codes are listed there.

Any other dashboard lights on? Water-in-fuel? I would suspect a fuel problem since he just filled up.

P0602 Powertrain Control Module Programming Error

P0253 Injection Pump Fuel Metering Control A Low

P0688 ECM/PCM Power Relay Sense Circuit

P0693 Fan 2 Control Circuit Low

Sounds like a real PCM problem..........
