2003 Ford F-350 Super Duty Problems

Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern. This issue can affect all diesel F-350, F-450, F-550, F-650, and F-750 Super Duty models.

The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

2003 Ford F-350 Super Duty Recalls

ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH 7.3L DIESEL ENGINES, THE CAMSHAFT POSITION SENSOR LOCATED ON THE ENGINE OF THE VEHICLE MAY FUNCTION INTERMITTENTLY, POSSIBLY RESULTING IN AN ENGINE STALL.

Ford has recalled 2003 Excursion and F150, F250, and F350 trucks because the speed control deactivation switch may leak and overheat, which can create a fire hazard. Dealers will install a fused wiring harness to the deactivation switch wiring.

On trucks equipped with the 6.0L diesel engine, the engine ground stud for the negative battery cable may be loose. A loose ground may cause current to flow through the radio suppression strap causing it to heat up, and potentially melt or ignite nearby components, which could lead to a fire. Dealers will replace the engine ground stud and the radio suppression strap, and nearby components will be inspected for damage. The recall began July 23, 2004. The Ford recall number is 04S15.

As far as the paint or clear coat coming, this problem would be from the factory when painted, the primmer coat might have been bad,clear coat problems is pretty much the same.
