bleeding fuel lines after head gasket replace
Hey fellas i used the search button and read and read but didnt run across anything about head removal and replace involving cracking fuel lines and bleeding.
Anyway i had to pull my head to get a glow plug out and everything is back together and no leaks, i have preassure at the schrader valve(however its spelled) and cant figure how to crack open the lines and bleed at the head. It has new plugs, new injector orings(yes they are installed correctly hard to mess that up, all injectors are seated correctly), new fuel bowl, new fuel filter, fresh fuel, good glow plug relay, starter kicks engine fine, before installing new plugs cranked engine to purge oil from doing injector orings, zero burnt connectors for plugs or injectors, new fuel lines in valley, fuel in filter bowl.
I havent yet checked the actual pressure with a guage but i cranked and bled air from the valve and repeated till a strong shot of fuel came out and now no air but only fuel. I know i have pressure there just not sure how much(do i need a liquid filled guage to get a reading on that or could i use a tire preassure stick guage. I dont see how a stick guage could give me a good reading but it may).
Anyway ive been cranking and giving small(very small) mists or dusts of starting fluid at the intake not in as to not over do it and it kicks the engine but it wont run cause there isnt fuel at the injectors. Brand new fuel bowl and again no leaks as well as there is fuel in the tank i am using. It is selected to the rear tank right now and i did drop the tanks to clean them(sat for 5 years under previous owner). Before i did i blew the lines back to the tank. After i did this of course i read not to put preassurised air to the switch valve between tanks but i select rear and it shows fuel so it should be good right.
Anyway done rambeling just trying to let yall know where im at any input is appreciated, do i just need to keep cranking this thing. As a side note truck did sit for 5 years with no cranks or runs on it. I replaced all the wiring with a good set of harnesses but would the sensors go bad while just sitting like that or the idm? I plan to buy the swamps idm but before spending the money wanted to crank it to make sure it ran alright.
