Soooo, my buddy and I spent all day on chasing what we thought was a VST issue. After replacing all the fuel lines, the plugs, and the water separator she still turns over like a champ but will not start. Looks like I am not getting the ground from the ECM to turn the High-Pressure Pump on. We jumped the pump to ground and we tested the rail pressure and it read 60PSI, not the normal 36-to 34PSI. Pulled the plugs and they did not look overly wet. We did check for spark and it is there. I am thinking it is the ECM not grounding the high pressure pump of firing the injectors, but everything I read says that it is pretty hearty and does not fail often. What are we missing?
