UPDATE:

We made an appt. with Ford to hook it up to the machine and try to figure this out once and for all. Our mechanic knew we were going to come pick it up the next day to put it on a trailer...

Check the fuel injectors. Take the valve cover off and look at the exhaust part of the injector when it is running.



Well, because the truck will not start he is not able to check this.

He...

Okay, I printed out this info and will pass it on to him tomorrow.

Any chance you can tell me something about the 2 oil pressure switches/sensors in the HPOP oil galley? My mechanic has asked me...

Does the engine have to be running to check this? If so, there is no way for him to check it.
Maybe I am misunderstanding what you mean, please tell me if I am. I wish my mechanic had a computer -...

As I stated in my original question,...

On a Ford Powerstroke 7.3 Diesel High Pressure Oil Pump, what does the Oil Pressure Sensor on the oil reservoir do? It does not appear to be attached to any light or gauge that would show a drop in...
