Have problem starting my 2000 F 450 unless it is pluged up. Have changed the glow plugs and the controller. They work like they are suppose too. Have also installed an LED in the cab to indicate that they are on. The engine runs fine down the road and pulls great, but just won't start when it cool or cold. The only way to start it is to use gas on a rag or either if not able to plug it up. Then it runs real rough until it warms up.
This started all at one time and I haven't found the problem yet.
Note: I have a superchip in it , and have reverted back to the original setting and still the same thing. Could it be the O-Rings on the Injectors or the High Pressure pump. This has me dumbfounded. I am a mechanic by trade but have little knowledge of the 7.3
