- The IP internals are whack (usually 180)
They run crappy when 180 out, but they do run.Here's the general idea: When the engine reaches #1 TDC, The internal IP camplate pushes the plunger into the HP (high pressure) head (toward the driver' side). The exact amount of push is measured with the gauge. So, if the engine is at TDC and turning backwards, the gauge reading should reduce as the plunger backs out of the HP head.
I'd also check that the gauge is not binding, by gently pulling on the top of the pin (has the knurls).

Having the pump internals 180* out will not show any issue during the gauge part of the timing procedure. You won't notice it until you attempt to run it Impossible to be 90* out and have the pump go back together.I think unfortunately here it is just a lack of the know-how. Your pictures show that you do have everything lined up correctly. You can see his TDC mark, and the pump is in the center of its moving area. You can also see in the pump shot that the pulley is at TDC as well, by the small gash in the one rib.You go from 2.29mm pre-load at TDC, and then rotate the engine Counter Clockwise to 4.74mm? Even if you went clockwise the gauge would only go up to a certain spot and then go back down, to the same lowest spot it would go to by turning counter clockwise. You are probably just turning the pump the wrong way. Small things.
