Low fuel pressure on my 2000 Silverado 5.3
No start symptom. Took the chevy dealer and they
looked at it and said the fuel pump was bad
causing the low fuel pressure. 50 psi. I bought the
truck home and change the pump. Still no luck 50
psi at the rail.
Changed the filter. No luck. 54 psi at the rail.
Changed the fuel regulator. 52 psi at rail.
Pulled line off filter and checked the pressure out of
the pump. 80-90 psi. Where do I go from here?
