I have an 03 cummins 5.9 with 64k on it. It ran fine when i drove it on thursday and it was fine and now today it won't start it cranks over but doesn't fire. I got code p0480 off of it. It says it has to do with the fan clutch relay. I looked in the fuses and relay box and couldn't fond one that had that label. Help o need to get my truck running for work on Monday.

 

Probally the electric fuel pump at the fuel filter housing is shot. Common problem if it hasn't been replaced yet check that first.
