2003 Ford F-250 Super Duty Problems
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.
A coolant leak from the radiator can be caused by a defective thermostat bypass. This can cause pressure spikes in the cooling system, which leads to radiator failure. The thermostat assembly and radiator should be replaced.
The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

2003 Ford F-250 Super Duty Recalls
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.

I have a F-250 2003 with a 5.4 gas engine, I bought it used this past summer. I have noticed the truck seems to seem as if it is bogging down when I'm going about 70mph. I have to keep acelerating. Now my truck will run fine for a few days and then it will die if I stop or decelerate. I've checked the fuel pressue while it was ideling and it was 30psi. But I think the fuel pump is going out.

It will start out fine after we put it on, then any slight movement and it will lock up and any m...
