So I have a friends 88 C1500 4.3 TBI and it has no fuel pressure. The pump and regulator were replaced about a year ago and it ran ok, doesn't get driven much, just to the dump once a month. I hear the pump buzzing but no pressure on gauge so I replaced the P/R just for ***** and grins, no luck What am I missing? Is there some way to block off the return line and see if it makes pressure? Thanks for any help with this problem child.
