Hpop

[race14race]

ok my truck starts then dies and wont start back until the next day... i checked the hpop. it was about 2 inches from the top. refiled it and cranked it, did not start and rechecked it was empty.. my screwdriver hit metal with no oil on it. how much does the resovior hold and y isnt is staying full? i was driving down the road and the check engine light came on, and it quit.


so how does the the oil system work?

SOunds like your cps to me, does your tach move when you are trying to start it?

[race14race]

yes it does

sense this truck is a 1994.5, i heard there was a drain back issue with the hpop. can anyone elaborate?

[Turbodude]

ive wondered how they back bleed too...ive never understood it so this will be a learning expirience for both of us

so how do u keep your truck starting?

sounds to me like if your oil reservoir is low ,your not getting oil out the pan ,2 things can cause this , one thing to check ,pull off the oil filter and look at the aluminum housing , there is a valve that is supposed to be there , they are bad to fall out , if its missing that is your problem ,will not pump enough oil to keep hpop full and engine wont run ,start there and let me know ,well go from there

The HPOP pumps oil, not diesel fuel.

ok good. it seems to stay full now.. witha good hot battery it will start and run for a min or to and then die. the resivior is staying full now. maybe i have a dead cell in a battery? they both show over 12 volts on a meter
