7.3 wont start
so my trucks been down for over a year now and i'm determined to fix it now.
i had my truck at my dads sitting for 6 to 8 months decided i was going to drive it went out there started it up and it idled for like 15 mins and died i tried to restart it and nothing.
i replaced the cam position sensor still nothing
took it to ford they said it was the idm
brought it home swapped the idm and nothing
put a post up on here and someone said to check oil pressure i did and got nothing
replaced the lpop
i still cant get any sort or oil pressure any ideas/ help would be great thanks

Take the plug out of the driver's side on the top of the HPOP reservoir, and use a small funnel and fill it up to within 1/2" of the top with new oil. Crank the engine a few times. Repeat as necessary. The LPOP will prime once the engine starts. And the engine can't run without LPOP pressure to feed the HPOP, so you won't be doing any damage to it.

And the dash oil pressure "gauge" isn't worth a crap for anything. It's just a switch; it opens up at around 8 psi, and whatever it shows after that is just wherever the gauge decides to sit. It's a glorified idiot light.
