My 2002 250hp EFI will turn over- but will not fire, the injectors will spit , no spray- Thinking bad high pressure pump bad- what is the correct pressure?

Can you hear the pump running

[rangerc375]

pump on

yes, the pump is on- un hook fuel rail the 6 injectors just spit , no heavy flow or spray

Should have 30-35 psi fuel pressure on OX66 models or 35-52 psi on HPDI models.
