Having problems with your 2002 Ford F250 Super Duty SuperCab ?
7.3 liter will not start.
\015 The low pressure side of the fuel system is ok, we have fuel to the filter and I would assume to the fuel rail as well. We decided to install a pressure guage on the high pressure oil line from the pump to the valve cover and when turning over the engine we see no pressure at all therefore no fuel pressure to the injectors. We thought maybe cam position sensor but we are not receiving any engine codes while turning the engine over. Is the high pressure oil pump knowing for quitting on these engines?\015
Yes they are you stated that you have mech oil pressure did you install a gauge?. this is a fuel line pressure sensor on the right bank at the frt of the head this sensor is rail pressure that high pressure oil pump creates check you pressure there that will elimnate that head the other side is a little more of a pain to test. one other thing to keep in mind is that the cranking speed is very important, and have you checked the oil level on a 7.3 deisel if you are more than 3 qaurts low on oil you will trap air in the high pressure pump. this will cause a hard start our even a no start
