glow plug relay?
Which 30 amp fuse are you blowing? If it is for the fuel heater, which also controls the "wait to start light". Disconnect the electrical connector on the side of the fuel filter housing and see if it still blows. If it doesn't blow, replace the fuel heater.- Toptech

Exhaust Back Pressure Sensor
That's what Ford says anyway. It appears to be used kind of like a position sensor, By reading back pressure the pcm knows the position of the EBP Valve. If the valve were to stick closed or partially closed the pcm would read higher than normal back pressure. And, if the line to the EBPS were...- Toptech

Exhaust Back Pressure Sensor
This should answer your question.

Tranny Question
This could happen, but look at it this way. If you don't change the fluid, the trans will definitely go out eventually. The old fluid is just going to cause more damage the longer it is in the trans.- Toptech

Dead 7.3
Not nessasarily. Static compression could be fine, may only leak under extreme cylinder pressure (turbo boost). The best test is to check for combustion gases in the cooling system. Any good engine tech will have the kit needed to perform this test.- Toptech

Dead 7.3
I'll take three of them at that price! You may want to recheck the price, it seems to be just a bit low. But getting back to the original problem. If a shop told me that blow-by was pushing coolant out the degas bottle and causing the engine to overheat; I would be taking my truck to another...- Toptech
