Early 99 no oil pressure in hpop reservoir!!!
ok the other day i was driving along and noticed my op gauge on the dash drop to 0 and the dummy light came on.. me knowing the truck wont run with out op drive home. i replaced the op gauge switch and still read zero so i put a manual gauge on the hpop res. and started the truck, it stays at zero... im at a loss here on this thing. i have changed the oil and filter thinking maybe the filter collapsed and it still reads zero. if i rev the truck up to 2k it reads 5 psi but anything below that its at 0, idk what to look into from here. all info is greatly appreciated. TIA!
