HPOP or IPR problem -- internal leak?
The other day my 99 F250 wouldn't start. After poking around a bit, I opened up the HPOP reservoir and discovered it was bone dry. I filled it up (and made sure the engine oil level was right), and it started up after a few seconds. I ran it for a couple of minutes and everything seemed ok.
A few days later, I tried to fire it up again and there was clearly no fuel getting into the injectors. So, in a few days the HPOP reservoir dried up again.
There is no oil on the driveway and no leaks i can see. so i assume the system is leaking the oil internally. I have done some research on this (mostly on this site!) and i keep seeing HPOP and IPR coming up. I am not a very experienced auto fixup guy but i am really trying to learn how to care for this baby.
also since the engine seems to sustain itself once i fill up HPOP reservoir i have figured its not the low pressure oil pump...?
Appreciate any tips or help.
