Low pressure oil pump feeds the hpop. There is s check valve in there too. Could be as simple as a $10 part.

Click to expand... What he said.. would be the things to check & eliminate first ? But.. it takes 500 psi HPOP pressure, minimum, to pop the injectors @ start-up. A good Scanner would detect that.
