No no, the pressure read good on my friends pressure gauge, but my gauge, and a GM dealers gauge both read super low, 49 - 50psi idling.
I believe my friend had a faulty gauge that was reading pressures too high.
However, the new pump is basically sending the same pressure, which means 2 things, first, the old pump was probably fine. Second, there has to be something between the pump and its power supply, or fuel lines that's causing the pressure to run so low.
I am going to change the filter again, and do a pressure check there today. If the pressure at the filter is the same as the rail, the lines are fine and the pump or power supply will be the focus, if the pressure is higher at the filter, then there is an issue in the lines somewhere for supply.
That's about all I can figure at this point.
