Fuel rails getting fuel but not at pressure ALH

[Ian Keeffe]

When I switched pumps I kept the cap out of ease. The check valve for the fuel return from the injectors was bad and sending all the fuel back to the tank. Switched the cap and I’m running great! Thanks for the input all

The check I did for the cap which is what I would recommend for others to test before swapping pumps is clamping the black return line and opening the injectors. If they spray with that then it’s the check valve in the cap

"Okay so now there’s conflicting info. If I opened it two whole turns, should it spray up more than one inch?"

If there's conflict between what I and Oil say, certainly go by his experience.

Yea he was right. It just took the new cap and I was getting large amounts of spray no matter how loose it was
