I should have asked if you filled the secondary filter, not the primary.
When you say there is plenty of fuel going thru the primary filter but none going thru the injection pump, where are you testing this? The fuel flows from the tank thru the primary filter, into the lift pump, is pumped by the lift pump thru the secondary filter and then into the injection pump then out the hard injection lines.
Where in that route are you saying that the fuel stops?

The fuel seems fine
at the secondary filter. From there, I'm pretty sure we only looked at the block side of the hard lines where it was intially alright then later, dry as a bone. I don't think we looked at the fuel leaving the secondary pump. For which it requires the lifter pump to pump fuel
past the secondary and into the hard lines? I just spoke with the mechanic on the phone and asked about it and he said he checked the hard lines at the injector side and nothing. I apologize but I don't remember.
If someone would prefer to communicate directly with him, his cell is 573 261 0182 He might have a more accurate description, mechanically speaking, as a certified GM mechanic.
